This sounds kind of familiar, doesn't it?

A dispute between Baltimore County police officers and a man that filmed them arresting two people in Towson, Maryland, is raising questions about civilians’ rights to videotape cops.

Officers became combative when the bystander refused to put away his camera. One told the man to “get it out of my face.” Another officer told the man to “shut your fucking mouth or you’re going to jail.” The man later said, “I thought I had freedom of speech here,” to which an officer replied, “You don’t. You just lost it.”

Here's video:

You'd think police officers would be told in their training that civilians are allowed to film them at their job. But I guess in police culture, training is considered to be a kind of punishment, right? So maybe their training is just so traumatic that they forget everything they learned. Poor guys.
