hopefully you realize that every person has THAT "button" that will push that person overboard... for some, it is a baby crying non-stop on the bus while you are travelling from Miami to NYC... for others, it is the dumb boss that is asking impossible, and at the end promotes a total ass-kisser, and bypasses you... for the others, it is that jerk in that expensive BMW (i had to bring BMW into the picture!!) who thinks he is the king of the road, and almost clipped you...

So, some people are reaching for the tire iron, or grab a suitcase and throw it or... or, they reach for something that is more convenient and scary...
As long as you know, that guy on the escalator was at the end of his rope, and all he needed just that last straw... Don't you watch the news, when on Black Friday people brandish their guns? The pilots undergoing psycho evaluations every so often.. the LE people are taking special tests.... doctors have gazillion tests... people who are capable of taking other people's lives in their daily routine undergo a lot of evaluations... a regular Joe-Shmoe might be seeing shrink but chances are - not...

If there are NO weapons in amateurs' hands, there are less chances of making a mistake - bad enough, we have just about every Joe-schmoe driving a car without knowing what the hell they are doing... and part of the point is - why does my mother need a gun? she is NOT trained how to handle it, she is NOT part of the State sponsored and well regulated militia, and probably poses more threat to society with a tool in her hands that she can't use (if she had a power drill in her hands, I'd be worried almost as much!!!). that is the point - too many guns in the hands of the GOOD people that have no business of having those guns...
