I have no idea if his "threats" are illegal or not but I'm pretty sure that it could be argued to a point where a judge would throw out claims that they were actually threats.
Chris really thinks like a child so he makes threats like a child. He want's all his enemies d-e-d dead and the place he hates to be blown up and wants other people to do it for him. He similarly threatened to kill the esteemed Mr. Cash too (with a knife unless I remember this wrong) and Clyde didn't even get so far as to get one bite of his own underwear!
generally a threat has to be credible before it's considered a crime. You can threaten certain high-ranking political officials and while you're gonna get an extremely unpleasant visit from some jerks in black suits and sunglasses, you're probably not getting charged with anything if it turns out that you were just running your mouth.
for a threat to be credible, it has to be somewhat specific
and backed by the present ability to carry it out. Saying "i wish someone would kill ________" is really fucked up, but it's not illegal unless it can be proven that you're genuinely asking or inciting other people to make it happen.
