This juvenile gal is working the drivethrough when she waits on a cop. He insists that he gave her a twenty. Even after the manager checks, he doesn't believe them. He arrests and juvenile and during the process sprays her full in the face with pepperspray. Watch the full event - look what is caught on video.

This is not new, but worth watching.

He's fired, but soon gets rehired by the police force.

Now what this tells me, on a common sense level, is that even when cops are clearly wrong, you can't touch them.
