Easy way to see if a vet is a right wing extreme terrorist: Cops show up to his house with a warrant, if he goes for his gun - kill him. These are terrorists we're talking about, terrorists have no rights. They can hide incognito but when their feet is to the fire they'll die trying. Trust me, i'm a vet.
....wait....
what if they shoot me and plant a gun on my body?!?! I take it back, I take it back, that's a horrible idea, terrorists do have rights, we just need to catch them after they kill people.
But how can I sit idly by and let terrorists kill people? Ban guns? But then they'll just get a super soaker, fill it with gasoline, go to a black friday mob, super soak the mob with gas, toss a zippo and walk away like a badass... maybe we shouldn't allow people to pump their own gasoline, that's what Oregon does.. but then they'll just attach spikes/cowcatcher to the front of their truck and plow through the mob... I guess the best way to prevent right wing extreme terrorism is to arrest them before they can strike... maybe that's what the NSA is for...
