The point is to not get their attention. Give me 6 lines written by the purest man alive and I'll find a way to hang him. Which they will do even if they find out you weren't the droid they were looking for, just to CYA. Been there. Only some very cool stuff in my FBI dossier saved me, once I got them to go read it.
I guess I've never related the story of my little visit from the DEA here, based on profiling. No drugs found. But they took all my guns out, stacked them on the bed, and got some bags of white powder out of their truck, piled those on, and took pictures, just in case they needed them for something.
It's quite a story, and I ought to write it up for here so people will know what to expect if a bunch of guys dressed in black show up with guns - and where they *didn't* look...as well as where they did. They broke every law in the books, BTW.
Refused to ID themselves. Didn't have a warrant until 45 min *after* the no-knock breakin. Stole things. I beat the snot out of them in court later (they did find some contraband, and charged me for it, but it wound up null-prossed - it never happened).
