Police (federal, state/provincial and municipal) have manipulated data before, and not always for the good. There is a growing school of thought that "if you have nothing to hide then why not". I don't buy into that thinking. The onus of proof has to remain with the prosecutors, not the defense. Someone says to me, "You shouldn't be offended that governmnet wants to know what you're doing 24/7 because if you have noting to hide then you have nothing to worry about." I reply, "Same back atcha. You won't mind your next crap (bowel movement) being filmed in case there is any future doubt as to where you were at 7:36 AM, June 15, 2007." Sorry. Yesterday, today, tomorrow: I don't trust government all that much. And in fact they have given us very little reason to trust them. IMO.
