Guns are not the problem, the problem is a lack of common sense,
that leads anyone to think that violence is the only answer to a problem.
So here you have "You not take care of mom, so I kill you" Where is any kind of logic or sense here ? How can anyone pull this reasoning out of the air ? You have to be stupid or crazy to think this way.
So Sad to see so much of this in Thailand.
Maybe because if you are the one who is wrong, you lose Face.
So you can not admit it to yourself or apologize, which puts
you on the path of confrontation and violence.
