Here is the issue: We have folks here demanding that cops basically 'do something!' Why on Earth should cops be watching, even engaging in conversation with someone doing "nothing wrong?" We all know the reason: This is extremely unusual and odd behavior, so much so that even if it is legal, the rabid 2nd Amendment supporters here want the person checked out. Why? Because there might be _danger_!! Why else would Joe Williams and you understand, and maybe even request, that cops watch someone who is doing nothing wrong? Again, we all understand that this type of behavior is extremely unusual. Not only that, the _only_ real difference here is the cop leveled his barrel higher than the guy with the AK. If you want cops to check out these people doing nothing wrong, because there might be _some_ dangerous issue that needs to be addressed, then they are going to take steps to secure their safety. In this case, what is the best way to confront someone _holding_, in a ready to fire manner, and AK-47? If the cop who pointed the gun at him thought this guy was breaking the law, then putting him at gunpoint was the sound thing to do. However, if he wasn't/isn't breaking the law, and I know that, and you folks make it so I can't take pro-active steps to protect myself when either "watching" him, or speaking with him, then I am going to do neither. I will drive by, cautiously, see it is a "pistol," and leave. I would likely not get that close to the person, as who knows if it is a nut case waiting to blast off a few rounds.
I am not a "blue canary" for all of you folks. I didn't sign up for involuntary suicide. That being said, I try my best to be familiar with as many laws as possible. I can deal with possible "quick draw" type situations, where I am dealing with folks with holstered guns. However, if the target of my investigation already has a drawn gun, I don't see why I can't have my gun drawn as well? And if I feel the need to point it at him/her, so be it.
"Do something" is not license to do anything that strikes your fancy.
You seem to think that when the questions are about this situation and what was done in reaction to it that someone, somewhere else doing something else, is an answer. "What about the guy on a rooftop with a rifle checking out the street with binoculars?" Since the OP wasn't about a guy on a rooftop with a rifle scoping out the crowd with binoculars, it's not really relevant.
You know, I was creating an SF con "hall costume" (kind of Paladin meets steampunk--"Have Slide Rule, Will Travel" kind of thing). I got a western style "cowboy hat" for that and in the course of breaking it in decided I like it. I tend to wear Roper style boots. The high shafts keep water and snow out of my shoes; the smooth, rather than emproidered, leather polishes up nice for when I want somewhat dressier wear; and the bit of heel relieves my plantar fasciitis. I wear jeans a lot and tend to wear dark colors (my wife things I look best in dark colors, particularly black). So basically my attire is often some kind of cross between goth and cowboy.
Now, add in that I carry, sometimes open, usually concealed. So, what, if I'm open carrying or my shirt happens to hitch up over my gun does my look rise to the "extremely unusual and odd behavior"? Can I expect you to be pointing your gun at me should we ever encounter one another on the streets? After all, you might argue that I think I'm Wyatt Earp or John Wesley Hardin or something (I'm a bit old to think I'm Billy the Kid).
Do you respond to every call with drawn guns? After all, you wouldn't be called if there weren't a danger. When our first was born my wife went through some serious post-partum issues. As a result there were several "domestic dispute" calls. I'm told that domestic disputes are one of the most dangerous types of calls. Yet somehow I never was a drawn gun. Enough traffic stops have gone "hot" that pulling someone over for a ticket could be a danger. Do you always approach the car you stop with gun drawn?
The above is intended to illustrate that not all potential dangers are the same nor do they call for or justify the same response.
Yes, you want to go home safely at the end of the day but your safety does not trump mine--not to me anyway. And if you can cite a felon carrying a drawn gun in his hand in a thread about someone carrying an AK pistol slung while failing the fashion police, I can ask what's to stop the next Law Enforcement Officer holding someone doing "extremely unusual and odd behavior" (such as wearing clothes the LEO questions) from being another "Mr. Glock Forty". (I presume you know to whom I'm referring. If you don't, I can post the vid.)
The question that comes to my mind in these threads is: would you consider that Goth Cowboy who is either OCing or whose nominally concealed weapon prints or happens to get uncovered enough of a threat to face him with drawn guns? The responses I see on these threads do not fill me with confidence about that possible encounter.
