I have known and worked with many police officers in my life. A couple are my best friends. It is rarely the cop on the street you have to worry about. I have yet to find one that isnt pro Second Amendment. It is the Chief of Police, District Attorney, and politicians that you have to worry about. They set the agendas and procedures the street cops have to follow. Every police officer I have talked to on the subject says they do their best but they cant protect you 24/7, so you have to be prepared to protect yourself. Call 911 and Pizza Hut and see who gets there first.
Hey. I didn't mean to imply that the officers here are anti 2nd ammendement, though many are. But, without trying to draw too much of a generalization, many of them draw a distinction between RKBA and shooting someone in defense. I think it's important to point out that we, not only have to register all firearms and have a 14 day wait, but in many of the mandatory 'judicious use' classes, it's stressed that even maiming in defense is grounds for prosecution. The instructors do, however, point out that alive and in jail is better than dead; to which I totally agree. And i know some PO's, though by no means many and I'd guess that it's split fairly down the middle re: the 2nd.
Fortunately, as in my case and as I understand in majority of cases, it never actually gets to that point and merely brandishing (and a few choice words at full volume) is more than enough incentive for perps to evaporate.
