FILE - In this May 17, 2015 file photo, a McLennan County deputy stands guard near a group of bikers in the parking lot of a Twin Peaks restaurant in Waco, Texas. The prevailing images of protests in Baltimore and Ferguson, Missouri, over police killings of black men were of police in riot gear, handcuffed protesters, tear gas and mass arrests. The main images of a fatal gun battle between armed bikers and police in Waco, Texas, also showed mass arrests _ carried out by nonchalant-looking officers sitting around calm bikers on cell phones.
