They don't need to do something as crude as wiretaps. Just get a warrant (these guys print them all day long), go to the provider and say "give me every thing on (123)-555-1234." They get incoming, outgoing, times, call length, and if it is a smart phone, URLs visited and data packet info.
Piece of cake.
I think they are about to find out that if you kick your lapdog it just might bite you.
