Protesters torch police car as troops guard Ferguson

USA Today reports:

Protesters torched a police car in a second night of unrest Tuesday, hours after Missouri's governor sent hundreds more National Guard troops to restore order in this riot-torn city.

Tensions rose after darkness fell, a day after a grand jury's decision not to indict a police officer for shooting an unarmed black teen sparked violent protests.

Despite the presence of more troops, hundreds of protesters marched on City Hall, smashing windows and setting fire to a police squad car.

Police responded with armored cars and lines of officers with weapons and dogs. Smoke rose from the street after police lobbed what looked and smelled like tear gas. Protesters tossed projectiles back at police.

Obama voters come unglued.
