I said nor implied any of the inferences you put to keyboard. Good law enforcement takes patience and a stone cold calm. Of course criminals should be arrested! They should be arrested at a time and place of the choosing of professional police, not neccessarily when all the testosterone, adrenaline, and mayhem is playing a signifigant role on all comers to the ball.
Oh, of course! Officers should never try to arrest someone in the act of committing a crime. Let them finish up, make their escape and just look them up later. Rape victims and abused wives should especially appreciate this technique.
May I take this opportunity to say that you haven't a clue about what is good police procedure. If your alleged LEO neighbors thought a bank robbery didn't deserve their attention, then I extend that criticism to them as well.
I have been a police officer. I suspect you have not. I also suspect there are reasons the LAPD respond to bank robberies like they are serious, violent crimes in progress. That would be because they are!
Next time you're talking to one of your LEO neighbors, ask them if the LAPD is coming to them asking for advice on tactics and policies. I'd bet a lot of money that they are not.
