Requires certain municipalities in St. Louis County to disband their municipal police department and choose other options for the provision of law enforcement services in the municipality

HB 456 requires cities in St. Louis County with fewer than 5,000 residents to disband their municipal police departments within five years of the law's effective date. These cities must either contract with another law enforcement agency or eliminate local police services entirely. The bill directly affects small municipalities in St. Louis County (a county with over one million inhabitants) that maintain their own police departments. Key provisions mandate the timeline for disbanding and specify the two allowable alternatives for law enforcement provision. This is a substantive policy change impacting local law enforcement structures in targeted communities.
