Four Denver cops hit by speeding car during Ferguson protest...

A group of local high school students in Denver decided to hold a protest rally over the shooting death of Michael Brown in Ferguson MO.

Expecting only a few people to show up, the protest rally immediately swelled to hundreds of marchers and students walked out of school during the march.

The march then turned awry when a speeding vehicle rammed four police officers on bikes leaving one of them in serious condition needing surgery at a local hospital.

The driver of the car reportedly had a medical crisis while operating the vehicle.

The officers were struck as they monitored the students, in plain view of dozens of students and bystanders who watched in horror as the officers were ran down by the black Mercedes, one who was dragged under the black sedan for dozens of yards. 

"He was just lying there," Taylor Ellison, a sophomore at the high school, said of one injured officers. "His pants were ripped. He wasn't moving." 

Witnesses say the Mercedes — driven by a man in his late 40s — accelerated west through the intersection of Colfax Avenue and High Street into the officers and a group of pedestrians before slamming into an SUV in a Taco Bell parking lot nearby where it came to rest.

Already we have seen calls for violence and death threats against officer Darren Wilson.

Not a good day for these protesters. This whole Ferguson thing is beginning to look like less about justice and more about a vicious vendetta against all uniformed police officers.
