They SHOULD have searched her home and she SHOULD have been in jail awaiting hearing. If it had been you and me we sure as fuck would be but perhaps you're one of those that think the police SHOULD be above the law even when off duty? God you must hate Nike by now, right? Burned your shoes yet?
Search warrants are written in such a way that they cover everything. If you know so much about the warrant, what else did it specify?
