Do you think it's justified to shoot someone who farted?

Yes, especially if the fart in question is cut in an elevator or a car or some other small confined space.

Just wait until all the non-farting passengers have exited the vehicle or whatever first, you don't want an innocent person to die with the stench of some douchetard's breakfast burrito lingering in their nostrils.

I support prosecution to the foulest extent of the law, but for the public safety I would suggest a 'farter's prison', rather than pulling the plug. And the gas chamber would be like a vacation for these deviants.

Absolutely. Especially when there is a room full of people and someone farts one of those silent ones. Those are the worse. Those people should be executed.

Is it ok to shoot someone in the mouth that belches(burps) it is the same thing

Garrotte the bastard. Leave him in the trunk of his own car. They will think it's a mob hit.

Only if you shoot them with a gas jet from your butt.

Only if your mouth was open.
