911 dispatcher: Let me know if he does anything, OK?
Zimmerman: OK.
911 dispatcher: Weve got him on the wire. Just let me know if this guy does anything else.

"We've got him on the wire"?? Huh?
Sounded to my ears more like, "We've got 'em on the way". As in, police officers to witness you committing second degree! Not! LOL!
