FERGUSON, Mo. (AP) — A U.S. Department of Justice report summary obtained by the St. Louis Post-Dispatch says police responded to unrest in Ferguson in a way that antagonized crowds, violated free-speech right and made it difficult to hold officers accountable.

The summary cited “vague and arbitrary” orders to keep protesters moving that violated their rights of assembly and free speech.

It is part of a longer “after-action” report that looked at the way police in Ferguson, St. Louis city and county and the Missouri State Highway Patrol responded in the first 16 days after 18-year-old Michael Brown was shot and killed by a Ferguson officer last August.

The newspaper reports top police officials at those four agencies will receive the full report this week.
