IL HB3641

Creates a Statewide Enforcement Unit within the Illinois Law Enforcement Training Standards Board responsible for investigating and prosecuting matters concerning automatic and discretionary decertification of full-time and part-time law enforcement officers

Requires law enforcement agencies to perform comprehensive background checks before hiring officers, including criminal history reviews, national decertification index checks, social media searches for expressions of bias or support for terrorist/hate groups, and verification with prosecutors about impeachment disclosure lists

Establishes new definitions including "hate group," "terrorist organization," "criminal organization," and "public expression of lawlessness or bias" to screen applicants for affiliations with extremist organizations or discriminatory conduct

Mandates law enforcement agencies maintain detailed records for each officer including hire dates, separation reasons, complaints, investigations, discipline, and training, with requirements to report certain misconduct findings to the Board within 10 days

Authorizes civil penalties up to $1,000 per day for law enforcement agencies that fail to comply with reporting requirements after receiving notice of non-compliance, and makes failure to report a conviction under automatic decertification provisions a Class 4 felony
