Is It A Crime To Video Tape Cops?

Maryland is really something, man! If a police officer is allowed to video tape a citizen who is being pulled-over or arrested, I definitely believe the public should be able to video tape that cop, as well. (To keep them honest). Or we are living in a police state. (Excuse the pun). Common sense should tell one, that a public official, like a police officer, objecting to being video taped (or even becoming angry about it) must have something to hide, and is very suspicious in itself; There would then be nothing to prevent that officer from therefore abusing their authority to do whatever they want, just because they wear a badge. We all know of the abuses by certain bad cops caught on video tape in the past, that helped the victim and protected the public, by getting those cops off the streets, for example. It should never, ever be a one-way street, in my strong opinion. Scary stuff! But unfortunately, it seems to be happening. Let's hope this case is thrown-out of court, because it is an outrage, and a farce. And would not only set an incredibly bad precedent, but would also be an erosion of the civil rights of all citizens...
