I think I might Jump in here bt 223 . . .
I was actually at Walmart the other day and I passed by the sporting goods section. For the first time I took a real look at those airosofts. The one I held was a dead on replica of a real gun, and, it had no red tip (I thought they were supposed to, but I guess not)
If I saw a teenager outside of my house holding a ar-15 in his hand, I will first assume that it was an airosoft, then while I was thinking I would grab my portable phone and bring it to the room where I keep my guns. (No . . . in this day and age it is not unreasonable to assume that a hyped up teen might open up on a residential neighborhood with an AR. I have seen a real life video of two copy cat columbine teenagers that had leaked out onto the Internet. Someone had apparently got a hold of the video from the video cameras AND the actual 911 recording (being that the teen in question found it amusing to keep the cellphone line open to 911 the whole damn time) and they cut it together. I will tell you this, those boys not only killed, they killed laughing and with a smile on their face.
NO, IT IS VERY PLAUSIBLE that a teenager is capable of taking an AR into a neighborhood and "releasing some misplaced anxiety."
Upon peering out the window I would have waited, and watched. No bullets all the better, if there were bullets my first reaction will not be to shoot, it would be to protect my family. I would yell to every one in my house "Get down . . . theres a shooting!" or something like that, and THEN I would call the cops.
If you hit the deck your going to do pretty good against someone "bump firing" (as they call it) a semi-auto and randomly spraying houses. The phone hast to come first if you want to protect 1.) your family 2.) your neighborhood and 3.) yourself. WHY, because you might not win . . . If the Cops are notified, they are going to race their pretty quick considering the content of the call. You could get injured, or worse and then what??? Who's going to protect your family???
Keep in mind,
IF there were shots fired, you said yourself, a second "Assailant" appeared that you hadn't noticed before. If he was a REAL assailant, well, I am not Rambo, and I am guessing neither are you, so you VS 2 other AR's is not a possition that any one of us ever want to be in.
MY point, is that be it the best case scenario (airosofts) or the worst possible scenario, (psycoteens) you best bet is to first,
notify the cops . AFTER the cops are notified you can then make a tactical assessment depending what is happening. I learned a great deal from the LEO and friends in the military that I have known over the years, and I can tell you this, armed boys in blue dedicated to protect and serve is THE BEST possible thing you can have going for you when the SHTF. No phone call . . . no back up, and then you are on your own.
All that said, I do not feel that you did ANYTHING wrong. As long as you were calm and cool enough to ONLY BE ASSESSING the target at the time that you were peering through your scope. However, next time, make sure that you are near a phone, sometimes a cellphone can be more powerful then the sidearm at you side
