This and that
First. Who? Never heard of him. When I saw "shock-jock", all I could think of were Stern and Imus.
Second. Sovereign immunity. HM Government can choose to do whatever it wants and Savage has little to say about it. Heck, if the TSA put him on our own no fly list, it would be years and years before he would even find out to to find out how to appeal. Although I'm willing to contribute to HM favorite charity if the government will let him in, if only so we can ban him.
Third. The US has this strange concept known as extrajurisdictional power. Let's say it's legal to smoke crack in Absurdastan. If I do, I can still be prosecuted by the US, since I'm a US citizen. On the other extreme, let's say I'm a semi-dictator from some Central American isthmus country that is perhaps helping out drug lords. I could be captured during an invasion, tried and imprisoned in the US. Ooops, not hypothetical.
Fourth, I got an email telling me about a new Pam and Tommy video, but when I went to look at it, all the money disappeared from my IRA.
Scratch the last, different topic.
