Maybe, but your idea for a punishment is a total pipe dream. He will not get a significant sentence....if he sees any punishment at all. In the grand scheme of things a family member of this kid finding him and shooting him in the face as his family watches is simply more likely to happen.

Also probably not going to happen but....whatever. Thats the country we live in. 3 years from now he will be cleared of all wrong doing.

Why? To have his buddies in the system help release him early but still broken psychologically to abuse the family who had finally gotten use to a new normal without the red marks from the thin blue line? To have that shell of an abuser go out into the world, hating the people around him for not understanding that his reality was enforcing the distinction between the elite alpha wolf first responders in life and the glue sniffing degenerate civilians that need to be protected from themselves - except now he's not privileged. He's now one of the people he has grown to despise and he can't stand it. He grows resentful and eventually kills himself and/or those around him.

All at the tax payers expense.

Negative. There is no earthly penalty greater than death, which erases all joy or suffering they ever felt anyway.
