Guns in the NFL

I don't get the whole NFL player infatuation-with-guns thing. 

Plaxico Burress is the latest case. He testified before a New York grand jury about an accidental shooting last November. He could be facing three years in jail.

I recently heard Titans quarterback Vince Young explain how he carried a gun for protection.

We all know the sad story of Steve McNair, please don't tell me if he HAD a gun it wouldn't have happened. McNair was known to carry.

Former NFL player Keyshawn Johnson recently said on TV, that he believes about half the players in the NFL carry guns.

It's their right. It's constitutionally protected. It can't be taken away. 

Columbian soccer coaches--- now those guys SHOULD carry guns.  

But NFL players in the USA?  I just don't get it.
