I don’t know but he hired a lawyer and is all of a sudden apoligizing. One can be sued for anything, doesn’t mean the plantiff will win but a lot of times just the threat will accomplish the intended results. In this case the Palins get a lot of publicity and sympathy for a few thousand dollars( a bargain for any politician) All the swish gets is an attorney fee.
While I think the guy is the ultimate jerk, that doesn't mean he can't seek to get himself some legal protection as well. I'd be very careful about sending this guy any sort of message, because I'm sure he's looking for a reason to turn this around against the Palins because of a few kooks who may be contacting him in retaliation. He already pulled his Twitter account, but I'm sure his attorney has it archived.
