Very polemic story. Nothing scarier than crimes being commited by law enforcement men and women. Common criminals tend to have some kind of reason, even if twisted. What rationale can peole in uniform have? Except the pursue of pure power through brutal force and the sick satisfaction derived from it.
We have plenty of that over here. People say, half humorously, that in a lonely night, out in the streets, they'd rather be surprised by thugs than by military.
As for Peter, better fight an angry dog than an indiferent bullet.
