In voiceover, Captain Frank Canelli describes an armed felony in action, and the responce of his uniformed patrolmen. It’s a domestic dispute that has overflowed to involve waving pistols around. When John is hauled away in cuffs, his wife thinks the cops are just butting into her personal affairs. Of course, Canelli has to explain that it’s for the protection of not only her, but her neighbors.
John is no saint, and has a history of encounters with the law. But there’s something fishy with the arrest. Canelli sifts through the evidence to find a cop who didn’t follow correct proceedure. Now he has to call a pair of his patrolmen on the carpet to chew them out about the importance of proper procedures, and not bending the rules for personal convenience.
The audio cuts off a little short, but all that is implied is that John might be more than a petty arrest, and the botched procedure might have jeopardized the legal process.
