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?

To be perfectly honest: we talk like we haven't had practitioners centuries and thousands of years before us, when you know, they didn't have guns, and missiles, and more effective ways to kill people.

As individuals and practitioner, sure, we're 'able' to will actions and things into existences. But on the other hand we are hubristic enough to accredit the action to our individual persona, as opposed to thousands of events that occurred that let up to the events, and we're simply taking the credit for what happened.

I'm kind of a supercalvinist/closet-hindu, so I sort of found this idea kind of peculiar~ just my two cents.
