It's a few weeks old - sorry I didn't see it earlier.
I've been personally "interviewed" by the SS. At the time, I was frightened, but not roughed up, much like the kid. Somewhere in D.C there's a folder with my hand-writing samples in it, just waiting to be compared to some threatening snail mail the Pres may received. They can wait.
This was also my first run-in with an old boys network (got turned in by some local cops who didn't like my viewpoints on a BBS system), my first evidence that the Bill of Rights is more lip-service than actual enforced law, and my last time looking at a government employee with less than contempt and disdain.
