In the weeks since a judge found former St. Louis police officer Jason Stockley not guilty of first-degree murder in the death of Anthony Lamar Smith, protesters have taken to the streets nearly every night.

While most of the people involved acted peacefully, in several incidents police have arrested demonstrators, and in some cases used tactics that are coming under scrutiny for their legality.

As a result, the city of St. Louis and the St. Louis Metropolitan Police Department are the targets of several lawsuits.
