I know it's a terrible job to be a Wal-Mart greeter

But to be tossed about by a policeman just for doing your job is really too much:

Chattanooga Police Det. Kenneth Freeman will not face charges in an incident in which he shoved a 71-year-old greeter at the Wal-Mart in Collegedale to the floor after he tried to stop him while doing a receipts check.

Collegedale Police declined to bring charges, then the employee, Bill Walker, filled out a complaint himself. Collegedale Judge Kevin Wilson has reviewed the complaint and did not issue an assault charge.

In the incident on Christmas Eve, Mr. Walker said an alarm went off when Det. Freeman and another city police officer, Edwin McPherson, were leaving the store.

He said he reached to try to stop Det. Freeman and he was pushed against a soft drink machine and to the floor. He said the officer then hovered over him as he lay on the floor.

The policeman then threw another man who came to help through the plate glass. And Collegedale Police are not going to bring charges? WTF?
