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?

First of all, I agree. It would be a complete waste of time to go dropping celebrities. Though, there are very likely many people that have been murdered with psionics. It's just subtle. The news would report it as a car wreck, or a suicide, when in fact it may have been completely influenced by a murderous psion somewhere. Famous people are tougher to kill though, because in most cases for every person that hates them there are two that like them. If someone's liked by a lot of people, and especially if these people pray for them, protective thoughtforms may appear. This would make killing them quite difficult.
