If you live in a Democracy and vote you have this power. Several of the things listed are illegal to do, people in the US have recently been jailed for possessing pedophile cartoons, and there is an interesting test case in NYC on whether Cannibal and snuff fantasizing is illegal. You can search around for cannibal cop stories on this one. An NYPD officer was part of a cannibal/snuff fantasy/roleplaying site and got so explicit in fantasies that included tracking down real women (he didn't do anything, just talked about hunting them) that he was arrested and is awaiting trial. Again, he discussed these things online, but he did not act on anything.
