Can you Video the Po-Po? In MD NO!
An off-duty cop pulled over a motorcyclist in Maryland for driving 100 miles an hour and popping wheelies. When the cop got out of his car, he immediately pulled his gun, and the motorcyclist's helmet cam got it all on video.
But in Maryland, you're not allowed to record someone without their consent, and after the motorcyclist posted the video on YouTube, he was charged with illegal wiretapping and faces up to five years in jail.
(--Here's a report from CNN, and the raw video.)
