Which brings us back full circle. How do you enforce the law, while upholding the law, without arrests.
This part indicates that arrests are not the favored action:
Captain, I don't think a policeman should work like a dog catcher in putting criminals behind bars.
Dog catchers are primarily charged with rounding up loose unleashed uncontrolled canines in violation of local ordinance. They either respond to a complaint or observe a transgression first hand. If they don't capture the strays they are derelict in their duties.
Can the same not be said for policemen?
The quote seems contradictory to me.
