Why?
Unbelievable. This guy is showing little regard for the law since he got out. He’s already had two speeding tickets, and now he threatens his father in law with a gun? I mean, come on. I agree with his wife that he must really feel invincible after all this. This not normal behavior from someone who literally just avoided life in prison.
Your assumption of facts not in evidence is astounding, so I am forced to conclude you believe "Guilty until proven innocent," and he has not been proven innocent. That's why.
