Psionic Assassination Options

I read a bit about psionics and loads of people say it can be used to cause targets to have accidents and the likes. If thats true then how come not one crazy bastard has got his hands of a radionics machine and used it to make a famous actor they don't like have an accident? It wouldn't exactly be hard to get a picture of the target and since thats all you need wouldn't the real unpopular actors famous actors be at serious risk since everybody in the world can get a picture of them?

Yeah, it's true dropping celebrities actors and actresses would be clownish. As to the question though, there are numerous and powerful obstacles in the way. The main problem would be this: let's compare it to firing a gun, for the most, most part the gun people would be using would explode in there hands, or would have blanks for ammunition. Secondly, if a person was lucky enough to get a shot off, most likely they would miss, and after missing the target (or even hitting) someone with real power would probably take exception to some yokel shooting at people in their vicinity (and vicinty can be QUITE large) and it would then be all bad for the original attacker.

Having said all that, look at some of the deaths over the years of some of our most controversial/talented celebritries and you have to wonder if there was a person/group/groups going against them, Marilyn Monroe, James Dean, Jimi Hendrix, Jim Morrison, Brandon Lee, and even more recently Heath Ledger.
