Walker, a greeter at the Collegedale Wal-Mart, says he was shoved to the ground, and knocked unconscious by officer Kenneth Freeman. This happened Christmas Eve. Walker says as Freeman was leaving the store, he asked to see the officer's receipt. He says Freemen didn't stop so he reached out, and touched Freeman's arm to get  his attention. It was at that point Freeman hit Walker knocking Walker off of his feet. That is evident in the surveillance video you can watch on NewsChannel9.com.

Freeman has not been charged, but he has been suspended 28 days without pay for conduct unbecoming an officer, execessive use of force and improper procedure. That's the maximum penalty an officer can receive before being fired.

I spoke with Walker Monday and he tells me he has flashbacks and, since Christmas Eve, has trouble sleeping through the night.

No criminal charges have been filed. The Tennessee Bureau of Investigation is investigating.
