Tattoos and pornography makes sense. They are both unringable bells that scar flesh and lives. Well, there's laser surgery, I suppose for the tattos. There is none for pornography. Perhaps there will be a day when a young woman can submit to vile sexual himiliations and degradations on a visual medium, and be submitted a self destruct device of some kind which will erase all coipies the world over once the waves of regret begin. But even then there may be viewers who preserve it before this happens with antique Super 8 Brownie equiptment.
