As I said, he's more of a nuisance than a threat. He simply hasn't been enough of a problem to justify going through the trouble of getting rid of him.

That said, I suspect that the instant one of his antics causes a injury/death (or some other sort of serious damage) the authorities will be on him like white on rice.

In truth, the above is why I think he's an asshole.

Either he's smart enough to realise that his continued survival depend on not being particularly successful, which in turn makes him a swindler/con-man grandstanding for the camera's. Or he's actually serious in which case eventually he's going to get someone hurt or killed.
