Can the police tap my iphone?

I recently got into some crazy mess ware police thought i was prostituting. I'm 17 and i ended up getting arrested for it (bs) but anyways i had my iphone4s confiscated unfortunately police are *** holes and didn't give me my phone back when i got released which by the way wasent even with my personals when i was in juvenile hall buh point is they finally sent me my phone in the mail and when all this was going on they assumed i was being "pimed" (which by the way i wasent a prostitute in the first place) so i'm kinda paranoid that they did some crazy stuff with my iphone 4s does anyone believe I've been tapped and if so how do i know?
