Conflicts and open questions
- Per the use plan, most fixed units were bought by the city's Board of Public Service; 87 fixed units (about $4,000 each) and all vehicle units (about $16,000 each) were funded by the St. Louis Police Foundation.
- The use plan says readers feed the Real-Time Crime Center, data is kept 90 days, SLMPD does not share data with other entities through an application, and ALPR records are treated as closed under RSMo 610.100(3).
- The RTCC page says the center opened in March 2015 and uses fixed and mobile LPR.
