Re: Aren't there already enough laws?
I can sympathise with Backpage. If they are being sued it makes perfect sense to respond with something like: "If you think we've done something criminal, call the cops, and they can get a warrant. Otherwise, sod off." The problem is that there doesn't seem to be any functional criminal law or police in the USA so suing people is the only way to get "justice". (And if the victim is dead and doesn't have any family to sue on their behalf - perhaps they were murdered too - then nothing happens.)
