True. And I'd like to think that after a while, like anyone else, you get good at your job, and you start to learn what's what. I imagine that the cop could tell the difference between "restless leg" and "let's have fun". I'm sure he's done this before.
This is bogus. Youcan’t arrest and convict someone for tapping his foot. Even if it is a message, so what. That’s protected free speech. Even if he is cruising, the other can say no. So, where is the crime, here?
