Guys, how about contacting E-bay's report a problem. I'd start there. I'm pretty sure it's not legal to sell merchandise that isn't yours on there. And that little IA statute you found makes your case against the found/possession is 9/10th of the law crap.
If that doesn't work, what ever happened to a good old ass whoopin? Catch him in the act. Nothing like a good old confrontation to put the fear of god into a mofo.
If you guys can get 23 mofo's out to Camden to work, I guarantee you can put your heads together to catch this motherfucker......It's a good thing I don't still live there, if those were my discs on there, I'd be sitting in jail, and his "distribution warehouse" would be a pile of ashes.
