Well covered in many other more widely-read forums is this guys account of being arrested after failing to show his store receipt (and driver's license) upon exiting a Circuit City store in Ohio.
This boils my blood (and scares the holy shit outta me). I had a similar, much less severe run in with a store goon years back when I waltzed out of a local electronics store without producing a receipt. I despise being asked to account for my personal property when leaving a store. I'm not a criminal, don't treat me like one. If you saw me steal something, bust me. If not, fuck off. Leave me alone.
So I donated a few bucks to the guy's legal fund. And I'm writing Circuit City a letter (on actual paper) and mailing it (with an actual stamp), telling them that unless they resolve this, publicly, and in the above referenced guy's favor, the money I was planning on spending there this year (after getting my new high-paying job) for the new ~50" HighDef TV and DSLR camera system will be spent at a competing store. (I never said I wasn't a liar).
Don't fuck with my rights. Or anyone else's for that matter.
