There is no good excuse for shooting at police and firemen. That's prima facie evidence of a violent felony. That said, the guy deserves treatment.

However, said treatment should be administered while he is an inmate of a stockade or prison. He does deserve help, with both the PTSD and his drinking. And with his violent and angry nature. While society is protected from any additional episodes.

I don't see how there could be any other decision or outcome. There is no way PTSD excuses this behavior. None.

Unless someone wants to say that veterans have the right to start bagging first responders. Make it a sport.
