Until recently, I didn't know much about Lenny Bruce. I knew he was a controversial and groundbreaking comedian who had some trouble with the law, but that was about it. Now that I've watched a couple of documentaries about him, I can't pretend to know much more than that, but I do know that he was repeatedly arrested, prosecuted, and even imprisoned merely for performing his act at comedy clubs. In other words, he faced criminal prosecution because some people found his speech to be offensive.
One of the documentaries made a point of noting that it wasn't members of Bruce's audience who complained (which is the sort of thing we'd see today). Audiences at the time seemed to realize that going to a comedy club after midnight to see a comedian with a reputation like Bruce's might involve exposing themselves to some "obscene" speech. Imagine that! They were prepared to handle it like adults. Unfortunately, the police were not so forgiving. They dispatched officers to Bruce's shows to enforce archaic obscenity laws. It is hard to believe that this happened right here in 'Murica, but it did.
