Ok, i know this for a fact
THEY cannot prosecute you for anything they found in your house that was not listed in the warrant, you could be growing marijuana in your bedroom, have bomb building books out with a lead box with plutonium lableled on it and they could just look they can look thorugh your drawers but seriously get alml ur shit out of your house having to do with ur pirating, even taking a magnet to this PC HD tomorrow cuz if they do happen to get a warrant really fast and come tomorrow morning just hand whatever they have a warrant for to them, be polite and honor any requests they have (reasonably) get a good Lawyer dont cheap out, and even video tape what the cops do every second they r on ur property and show to ur lawyer, if and when u show up in court, be VERY respectable, dress very nicely and always end your sentences with "your honor" when talking to judge, look the judge and prosecutor in the eye when talking dont look at the floor or figit, talk with confidence and explain everything that happened, ud be suprised what little details can throw ur case right out of court.
That's all i can think of right now, I feel reallly bad for you and really hope u'll get aquitted, but a very important thing to do is eliminate anything that can incriminate yourself and talk to your lawyer about where you should go from there.
Good Luck man
