Over time, it's clear that this culture of enforcement actions being disconnected from the public safety needs of the community – and often to the detriment of community residents – has given rise to a disturbing and unconstitutional pattern or practice. Our investigation showed that Ferguson police officers routinely violate the Fourth Amendment in stopping people without reasonable suspicion, arresting them without probable cause, and using unreasonable force against them. According to the Police Department's own records, its officers frequently infringe on residents' First Amendment rights. They interfere with the right to record police activities. And they make enforcement decisions based on the way individuals express themselves.
