Arrests are mounting up as protesters angry over the Michael Brown grand jury decision stretch the limits of the law.

More than 400 people have been taken into custody since it was announced Monday night that Ferguson Police Officer Darren Wilson would not face charges for fatally shooting the unarmed black teen.

The decision led to two nights of violent protests in Ferguson, which included looting and the burning of several buildings.

Protesters have also shown their outrage in Boston, New York, Los Angeles, Dallas, Atlanta and other cities. (Metro Networks Inc.)
