Spitballing? Is that, like, offering advice on something about which you know next-to-nothing, but still want to put something up on the board regardless of however inane or useless it might be? Is THAT what, 'spitballing' is?
As far as the unlocked front door goes? We lived in a beautiful home, in a very nice neighborhood, and the town's large (80 + officers) police station was only two blocks away - So, how safe is that! There was, also, a plainly visible metallic sign on the right-hand lentil of our front door. It read, '
Warning: Guard Dogs On Premises. Do Not Enter Without Permission.'
The fellow who came into our home that morning had to walk right past that sign; and there is no way a sober, unimpaired person could have missed it! To this day, I've never quite understood how the fellow could do that - Drugs, or alcohol maybe? (However, since you've decided to dwell on this event, for your next, 'spitball' why don't you ask me what happened to him? It's another great story on, 'Why' being prepared and having an immediate means of adequate self-defense is so important.)
Another thing: What's with the, 'acting like a policeman' remark? Do you really believe that; or are you just trying to be humorous? What would you do if you were to turn a corner and suddenly see a large man severely beating a woman? Are you suggesting that if you were in a similar situation you wouldn't become involved? (I don't understand? How can you be so disinterested, so socially insensitive?)
Personally I think your advice, your obvious attitude, is remarkably antisocial; I really do. I know my parents didn't raise me to behave that way; but, as your comments suggest, the social climate in America is rapidly changing and, perhaps, not for the better! Indeed, today it might be wise (if not entirely moral) to ignore other people's hardships - Especially other people whom you really do not know! Times are changing! Neither, 'acting like a policeman', or being a, 'good Samaritan' seems to be as appropriate nowadays as it once was.
You're able to appreciate the idea of being socially concerned, and becoming personally involved in what might be an uncomfortable, or even a potentially dangerous social situation; aren't you! You're NOT saying that you'd quickly get up and walk out of a movie theater the moment you heard gunshots - Right? If so, then, why carry a gun in the first place? Do you read? Do you know what Hemingway said? '
No man is an island unto himself ....... .' (Look it up!) Personally I think that each of us, by nothing more than the simple fact that we exist, owes a certain humanitarian debt to others. Surely, you do too - Yes!
You know, the Obama economy is hitting America very hard; and people's behavior is now in a state of social flux, and rapidly changing accordingly. As for myself? I think the increasingly difficult economy, here, in America has a lot to do with the continuous rise in the ownership of firearms. If Americans weren't genuinely concerned, if they really didn't care about either themselves or their neighbors welfare, then firearm sales would be going down instead of continuing to rise - Yes?
In the foreseeable future I expect we'll, all, see more rather than less daily antisocial behavior. You don't really think that school shootings, assaults on police officers, random sniper attacks, and malicious bombings are going to suddenly stop and disappear, now, do you!
Sometimes a right thinking, morally inclined, and socially concerned person HAS to get involved - Even when a certain amount of personal risk must, also, be assumed. Isn't this attitude, this mature sense of social responsibility, a large part of the reason, 'Why' so many law-abiding Americans value their Second Amendment rights and deliberately choose to own firearms! This sort of concern, this sort of social motivation, probably has a lot to do with, 'Why' American gun owners spend so much time on so many internet gun forums, as well. (Or, at least, I think so!)
You don't really advocate NOT to act, 'like a policeman', do you! Have you forgotten the legal concept of, 'posse comitatus'? In case you didn't know it is one of the foundational concepts underscoring American jurisprudence! (Once again, look it up!) Because if your most recent reply to this thread is, truly, an expression of how you really think then, maybe, you should either sell your guns, stop carrying a sidearm, or move someplace else.
You do! Well, it's NOT showing. There is, also, an obvious basic philosophical difference between your personal scruples and sense of social responsibility, and my own. This being said, I see no further value in continuing this discussion; so I'm going to let you have the last word. (I think you'll enjoy that!)
