Replaces everything after the enacting clause. Amends the Department of State Police Law of the Civil Administrative Code of Illinois. Provides that the Department of State Police shall provide a Dangerous Persons Hotline to consist of a website and a toll-free number to enable a person to notify the Department if the person has a reason to believe another person is: (1) a clear and present danger to himself or herself or another person; and (2) in possession of, or has access to, a firearm. Amends the School Code. Provides that the Department of State Police shall, in cooperation with each school board, distribute appropriate materials in school buildings listing the toll-free telephone number and website established in conjunction with the Dangerous Persons Hotline, including methods of making a report, which shall be displayed in a clearly visible location in each school building. Amends the Firearm Owners Identification Card Act. Defines "patient" for purposes of the Act as a person who: is admitted as an in-patient or resident of a public or private mental health facility for mental health treatment under the Mental Health and Developmental Disabilities Code as an informal admission, a voluntary admission, a minor admission, an emergency admission, or an involuntary admission; or is otherwise provided mental health treatment as an in-patient or resident by a public or private mental health facility, unless the treatment was solely for an alcohol abuse disorder and no other secondary substance abuse disorder or mental illness; or a person who voluntarily or involuntarily receives mental health treatment as an out-patient or is otherwise provided services by a public or private mental health facility, and who poses a clear and present danger to himself, herself, or to others. Provides that each applicant for a Firearm Owner's Identification Card must submit evidence to the Department of State Police that he or she has not been a patient in a mental health facility within the past 10 years (rather than 5 years) or, if he or she has been a patient in a mental health facility more than 10 years ago submit the mental health certification required under the Act. Provides that the Department may order an applicant or a current Firearm Owner's Identification Card holder to undergo a mental health screening to determine if the person's mental condition poses a clear and present danger to himself or herself, any other person or persons, or the community if: (1) the Department has credible information establishing probable cause to believe the person presents a clear and present danger to himself or herself, any other person or persons, or the community; or (2) if the person was a patient at a mental health facility more than 10 years ago. Makes other changes. Effective July 1, 2018.
