I had this movie on VCR years ago, but I lost it, and I don't remember the name.
The main character was a cop with longish hair, and weapons were forbidden in the movie. There were some criminals who somehow had a new drug on the street that basically made 'em seemingly unstoppable (just an adrenaline rush really), but yeah.
It's a fairly old movie, I'd have to guess in the late 80s, early 90s. Anyone got a clue? :(
