Why I am PRO gun

I guess I am a little out of the loop here. I saw a video of an incident in Philadelphia from a few days ago of one person beating another with a hammer on a train.

So I followed up to find more video through CNN and then the link I included.

What concerns me is why do the fellow riders ignore what is going on? Why did they not stop it? I recall the HEROES on flight 93 did not turn a blind eye they did something about the attackers. If ONE person on that train had a concealed carry permit, and USED it, this crime would have been stopped right then right there and in my opinion should have been rewarded not prosecuted. Defense of others is considered a crime in the so called land of the free.
Many in my circle of friends believe that an openly carried sidearm with at least a six inch barrel should be legal. I agree with the thought. Although I think it should be any sidearm that is not easily concealed because I am .45 lover (1911 was a GOOD year) which is a subjective judgment. I am six feet four inches and over 300 pounds and have successfully concealed a full house .357 with a seven and 3/8 barrel while talking to cops at a late night coffee shop. While I had a friend who could not hide his .22 snub nose revolver (worthless POS(the alleged gun and the friend))
If just ONE citizen had done that and felt that the legal system would honestly evaluate the shoot he would have felt that he could stop the crime. Anyone remember Mr Getz (I dont remember the spelling just the name) also refered to as the subway vigilante? I can guarantee the person he killed threatened no more littler then he people with a screwdriver for their belongings. Kind of hard to threaten from a grave. Improves the species in my opinion especially if gotten to before they breed their genes back into my gene pool.
This is trigger for another thought that scares me.
Power is an aphrodisiac.
Gangsta's have power even if it is at the barrel of a gun.
Picture college well educated women being drawn to this power.
Picture the kids.
Extrapolate a few generations.
I will leave you with that chilling picture. Have a nice day!
