(720 ILCS 5/4-2) (from Ch. 38, par. 4-2)
Sec. 4-2. Possession as voluntary act.

(720 ILCS 5/4-3) (from Ch. 38, par. 4-3)
Sec. 4-3. Mental state.
(a) A person is not guilty of an offense, other than an offense which involves absolute liability, unless, with respect to each element described by the statute defining the offense, he acts while having one of the mental states described in Sections 4-4 through 4-7.
(b) If the statute defining an offense prescribed a particular mental state with respect to the offense as a whole, without distinguishing among the elements thereof, the prescribed mental state applies to each such element. If the statute does not prescribe a particular mental state applicable to an element of an offense (other than an offense which involves absolute liability), any mental state defined in Sections 4-4, 4-5 or 4-6 is applicable.
(c) Knowledge that certain conduct constitutes an offense, or knowledge of the existence, meaning, or application of the statute defining an offense, is not an element of the offense unless the statute clearly defines it as such.
(Source: Laws 1961, p. 1983.)
(720 ILCS 5/4-4) (from Ch. 38, par. 4-4)

(720 ILCS 5/4-5) (from Ch. 38, par. 4-5)
Sec. 4-5. Knowledge. A person knows, or acts knowingly or with knowledge of:
Conduct performed knowingly or with knowledge is performed wilfully, within the meaning of a statute using the term "willfully", unless the statute clearly requires another meaning.
When the law provides that acting knowingly suffices to establish an element of an offense, that element also is established if a person acts intentionally.
(Source: P.A. 96-710, eff. 1-1-10.)
(720 ILCS 5/4-6) (from Ch. 38, par. 4-6)
Sec. 4-6. Recklessness. A person is reckless or acts recklessly when that person consciously disregards a substantial and unjustifiable risk that circumstances exist or that a result will follow, described by the statute defining the offense, and that disregard constitutes a gross deviation from the standard of care that a reasonable person would exercise in the situation. An act performed recklessly is performed wantonly, within the meaning of a statute using the term "wantonly", unless the statute clearly requires another meaning.

(b) A person's reasonable belief that his conduct does not constitute an offense is a defense if:
(c) Although a person's ignorance or mistake of fact or law, or reasonable belief, described in this Section 4-8 is a defense to the offense charged, he may be convicted of an included offense of which he would be guilty if the fact or law were as he believed it to be.
(d) A defense based upon this Section 4-8 is an affirmative defense.
(Source: P.A. 98-463, eff. 8-16-13.)
(720 ILCS 5/4-9) (from Ch. 38, par. 4-9)
Sec. 4-9. Absolute liability. A person may be guilty of an offense without having, as to each element thereof, one of the mental states described in Sections 4-4 through 4-7 if the offense is a misdemeanor which is not punishable by incarceration or by a fine exceeding $1,000, or the statute defining the offense clearly indicates a legislative purpose to impose absolute liability for the conduct described.

Sec. 5-1. Accountability for conduct of another. A person is responsible for conduct which is an element of an offense if the conduct is either that of the person himself, or that of another and he is legally accountable for such conduct as provided in Section 5-2, or both.
(Source: Laws 1961, p. 1983.)
(720 ILCS 5/5-2) (from Ch. 38, par. 5-2)
Sec. 5-2. When accountability exists. A person is legally accountable for the conduct of another when:
When 2 or more persons engage in a common criminal design or agreement, any acts in the furtherance of that common design committed by one party are considered to be the acts of all parties to the common design or agreement and all are equally responsible for the consequences of those further acts. Mere presence at the scene of a crime does not render a person accountable for an offense; a person's presence at the scene of a crime, however, may be considered with other circumstances by the trier of fact when determining accountability.
A person is not so accountable, however, unless the statute defining the offense provides otherwise, if:

(720 ILCS 5/5-3) (from Ch. 38, par. 5-3)
Sec. 5-3. Separate conviction of person accountable.
A person who is legally accountable for the conduct of another which is an element of an offense may be convicted upon proof that the offense was committed and that he was so accountable, although the other person claimed to have committed the offense has not been prosecuted or convicted, or has been convicted of a different offense or degree of offense, or is not amenable to justice, or has been acquitted.

Sec. 5-4. Responsibility of corporation. (a) A corporation may be prosecuted for the commission of an offense if, but only if:
(1) The offense is a misdemeanor, or is defined by Sections 11-20, 11-20.1 or 24-1 of this Code, or Section 44 of the "Environmental Protection Act", approved June 29, 1970, as amended or is defined by another statute which clearly indicates a legislative purpose to impose liability on a corporation; and an agent of the corporation performs the conduct which is an element of the offense while acting within the scope of his or her office or employment and in behalf of the corporation, except that any limitation in the defining statute, concerning the corporation's accountability for certain agents or under certain circumstances, is applicable; or
(2) The commission of the offense is authorized, requested, commanded, or performed, by the board of directors or by a high managerial agent who is acting within the scope of his or her employment in behalf of the corporation.
(b) A corporation's proof, by a preponderance of the evidence, that the high managerial agent having supervisory responsibility over the conduct which is the subject matter of the offense exercised due diligence to prevent the commission of the offense, is a defense to a prosecution for any offense to which Subsection (a) (1) refers, other than an offense for which absolute liability is imposed. This Subsection is inapplicable if the legislative purpose of the statute defining the offense is inconsistent with the provisions of this Subsection.
(c) For the purpose of this Section:
(1) "Agent" means any director, officer, servant, employee, or other person who is authorized to act in behalf of the corporation.
(2) "High managerial agent" means an officer of the corporation, or any other agent who has a position of comparable authority for the formulation of corporate policy or the supervision of subordinate employees in a managerial capacity.

(720 ILCS 5/5-5) (from Ch. 38, par. 5-5)
Sec. 5-5. Accountability for conduct of corporation.
(a) A person is legally accountable for conduct which is an element of an offense and which, in the name or in behalf of a corporation, he performs or causes to be performed, to the same extent as if the conduct were performed in his own name or behalf.
(b) An individual who has been convicted of an offense by reason of his legal accountability for the conduct of a corporation is subject to the punishment authorized by law for an individual upon conviction of such offense, although only a lesser or different punishment is authorized for the corporation.

(720 ILCS 5/6-2) (from Ch. 38, par. 6-2)
Sec. 6-2. Insanity.
(a) A person is not criminally responsible for conduct if at the time of such conduct, as a result of mental disease or mental defect, he lacks substantial capacity to appreciate the criminality of his conduct.
(b) The terms "mental disease or mental defect" do not include an abnormality manifested only by repeated criminal or otherwise antisocial conduct.
(c) A person who, at the time of the commission of a criminal offense, was not insane but was suffering from a mental illness, is not relieved of criminal responsibility for his conduct and may be found guilty but mentally ill.
(d) For purposes of this Section, "mental illness" or "mentally ill" means a substantial disorder of thought, mood, or behavior which afflicted a person at the time of the commission of the offense and which impaired that person's judgment, but not to the extent that he is unable to appreciate the wrongfulness of his behavior.
(e) When the defense of insanity has been presented during the trial, the burden of proof is on the defendant to prove by clear and convincing evidence that the defendant is not guilty by reason of insanity. However, the burden of proof remains on the State to prove beyond a reasonable doubt each of the elements of each of the offenses charged, and, in a jury trial where the insanity defense has been presented, the jury must be instructed that it may not consider whether the defendant has met his burden of proving that he is not guilty by reason of insanity until and unless it has first determined that the State has proven the defendant guilty beyond a reasonable doubt of the offense with which he is charged.

Sec. 6-4. Affirmative Defense. A defense based upon any of the provisions of Article 6 is an affirmative defense except that mental illness is not an affirmative defense, but an alternative plea or finding that may be accepted, under appropriate evidence, when the affirmative defense of insanity is raised or the plea of guilty but mentally ill is made.

However, he is justified in the use of force which is intended or likely to cause death or great bodily harm only if he reasonably believes that such force is necessary to prevent imminent death or great bodily harm to himself or another, or the commission of a forcible felony.
(b) In no case shall any act involving the use of force justified under this Section give rise to any claim or liability brought by or on behalf of any person acting within the definition of "aggressor" set forth in Section 7-4 of this Article, or the estate, spouse, or other family member of such a person, against the person or estate of the person using such justified force, unless the use of force involves willful or wanton misconduct.

However, he is justified in the use of force which is intended or likely to cause death or great bodily harm only if:

However, he is justified in the use of force which is intended or likely to cause death or great bodily harm only if he reasonably believes that such force is necessary to prevent the commission of a forcible felony.
(b) In no case shall any act involving the use of force justified under this Section give rise to any claim or liability brought by or on behalf of any person acting within the definition of "aggressor" set forth in Section 7-4 of this Article, or the estate, spouse, or other family member of such a person, against the person or estate of the person using such justified force, unless the use of force involves willful or wanton misconduct.

Sec. 7-5. Peace officer's use of force in making arrest.
(a) A peace officer, or any person whom he has summoned or directed to assist him, need not retreat or desist from efforts to make a lawful arrest because of resistance or threatened resistance to the arrest. He is justified in the use of any force which he reasonably believes, based on the totality of the circumstances, to be necessary to effect the arrest and of any force which he reasonably believes, based on the totality of the circumstances, to be necessary to defend himself or another from bodily harm while making the arrest. However, he is justified in using force likely to cause death or great bodily harm only when: (i) he reasonably believes, based on the totality of the circumstances, that such force is necessary to prevent death or great bodily harm to himself or such other person; or (ii) when he reasonably believes, based on the totality of the circumstances, both that:
As used in this subsection, "retreat" does not mean tactical repositioning or other de-escalation tactics.
A peace officer is not justified in using force likely to cause death or great bodily harm when there is no longer an imminent threat of great bodily harm to the officer or another.
(a-5) Where feasible, a peace officer shall, prior to the use of force, make reasonable efforts to identify himself or herself as a peace officer and to warn that deadly force may be used.
(a-10) A peace officer shall not use deadly force against a person based on the danger that the person poses to himself or herself if a reasonable officer would believe the person does not pose an imminent threat of death or great bodily harm to the peace officer or to another person.
(a-15) A peace officer shall not use deadly force against a person who is suspected of committing a property offense, unless that offense is terrorism or unless deadly force is otherwise authorized by law.
(b) A peace officer making an arrest pursuant to an invalid warrant is justified in the use of any force which he would be justified in using if the warrant were valid, unless he knows that the warrant is invalid.
(c) The authority to use physical force conferred on peace officers by this Article is a serious responsibility that shall be exercised judiciously and with respect for human rights and dignity and for the sanctity of every human life.
(d) Peace officers shall use deadly force only when reasonably necessary in defense of human life. In determining whether deadly force is reasonably necessary, officers shall evaluate each situation in light of the totality of circumstances of each case, including, but not limited to, the proximity in time of the use of force to the commission of a forcible felony, and the reasonable feasibility of safely apprehending a subject at a later time, and shall use other available resources and techniques, if reasonably safe and feasible to a reasonable officer.
(e) The decision by a peace officer to use force shall be evaluated carefully and thoroughly, in a manner that reflects the gravity of that authority and the serious consequences of the use of force by peace officers, in order to ensure that officers use force consistent with law and agency policies.
(f) The decision by a peace officer to use force shall be evaluated from the perspective of a reasonable officer in the same situation, based on the totality of the circumstances known to or perceived by the officer at the time of the decision, rather than with the benefit of hindsight, and that the totality of the circumstances shall account for occasions when officers may be forced to make quick judgments about using force.
(g) Law enforcement agencies are encouraged to adopt and develop policies designed to protect individuals with physical, mental health, developmental, or intellectual disabilities, or individuals who are significantly more likely to experience greater levels of physical force during police interactions, as these disabilities may affect the ability of a person to understand or comply with commands from peace officers.

(b) A peace officer, or any other person acting under the color of law, shall not use a chokehold or restraint above the shoulders with risk of asphyxiation, or any lesser contact with the throat or neck area of another, in order to prevent the destruction of evidence by ingestion.
(c) As used in this Section, "chokehold" means applying any direct pressure to the throat, windpipe, or airway of another. "Chokehold" does not include any holding involving contact with the neck that is not intended to reduce the intake of air such as a headlock where the only pressure applied is to the head.
(d) As used in this Section, "restraint above the shoulders with risk of positional asphyxiation" means a use of a technique used to restrain a person above the shoulders, including the neck or head, in a position which interferes with the person's ability to breathe after the person no longer poses a threat to the officer or any other person.
