Apparently swatt-ing is a fairly new tactic that the far left is using to try to silence conservative bloggers. What they do is call the local police using skype so it can't be traced, and then report that they are at the blogger's address and have just shot someone. This brings the Swat Team running out to the conservative bloggers residence catching them off guard.
Get a bunch of cops running around with loaded guns who think they're about to face down a murderer, and accidents can happen. That seems to be the point of this new scam. The left will keep using it and eventually some right wing blogger will meet a cop who is a little too geared up for his own good, and the next thing you know someone will be shot. Talk about a 'chilling' effect.
I don't imagine it will apply to me or anyone here since it seems to be a fairly rare phenomenon pretty much exclusively being used by one leftist psycho and his cohorts. But I thought I should link the details all the same.
This is the best synopsis I could find that relates the disparate details of the story:
