When I was a very young L/Cpl in the USMC, back in 1965, we were instructed in the use of the "new" M-16 rifle. We hadn't been issued the weapon, but I knew how to use it. We were also advised that we would NOT be using the rifle in it's full-auto capability. Marines were trained extensively in marksmanship and also to only fire on an identified target. Generally speaking, Marines in Vietnam didn't usually run out of ammunition because of the "spray & pray" attitude that was so prevalent amongst the ARVN and other U.S. forces. That being said and a matter of historical fact, let me bring us to the here and now. It seems that virtually everyone is carrying some kind of handgun, either for self defense or to perpetrate a crime. Most of these folks have no training at all. In the past, I have arrested "bad guys" with any number of revolvers and automatics with the wrong ammunition in their pockets. I once discovered a loaded 12 gauge single shot shotgun with a 20 gauge slug already in the barrel. I'm not suggesting that all the bad guys are fools, rather I'm pointing out that most of them are. The same dynamics apply to honest, law-abiding citizens that have been forced to carry firearms in defense of their own lives and property. Many of us are senior adults with health issues. Some even have memory problems. Others are young and healthy, but have never considered everything involved in drawing and firing a weapon. Questions like; should there be a round in the chamber (it seems safer, but is it?), what is situational awareness? Can I escape without having to use my weapon? Have I spent lots of time on a range learning about the capabilities of my firearm of choice? Am I truly comfortable carrying a device that can kill another person(s)? Lots of questions. Now what do you do if you come out of the local MiniMart just as a bad guy has already fired several rounds at a member of an opposing gang, race, ethnic minority, political party or ??? Suppose a concerned citizen aged 47 years old, with no training, carrying a Glock 19 with a high capacity magazine, decides that he will intervene in this dispute and fire some shots of his own. What do you do, as a well trained concealed carry permitted bystander? Drop your Bud Lite, loaf of bread and bag of Dorito's? The shots are going everywhere because the gang-bangers don't care and aren't trained and so are the shots of the well intentioned middle aged concerned citizen. Innocents are being hit and it's complete chaos. Do you shoot all of the participants, some of them, none of them or do you run into the store and call 911 so that they can take a report?
