Review of Ties That Bind

'cop killer' machine guns ? CPD just wandering out of state for undercover? And, of course, at a 'gun show' - where so many illegal transactions are made, and most anyone can just walk in and find someone to sell them homemade illegal cop killer machine guns ? And, just What Is a 'cop killer' machine gun anyway ? This doesn't even start with the time and mileage problems from the 'Loop' into rural Wisconsin (for the writers-it is NOT a 'few minute' jaunt) I normally love this series, but Come On Writers...UnLeft and UnP/C yourselves !! Please don't ruin an otherwise good show.
