Why are Bertuzzi et al and Bill Maher (et al?) not charged with premeditated x and premeditated y?

At another OP there was a post that said we need evidence to charge/arrest anyone with anything. This OP was my response (as an aside) but it was removed (off-topic).
If all that is needed is evidence, the evidence is there on the screen that Bertuzzi and others who assault premeditatedly, and Bill Maher who works hard to get people on drugs, send them to their death even, all in the name of comedy. article

“If one child anywhere in this nation falls prey to this Monday, I sincerely hope Maher and HBO are held responsible.”

So why don’t they get charged?
