They have no business charging the man. They might need to physically restrain him from interfering with the EMTs' work (although apparently it would have made no difference).

But why charge the man? No jury will convict him. Temporary insanity. Whatever.

This is a police state run wild. The sheriff's opinion that he 'crossed a line' is self-important bilge. Guess what, Mr. High Sheriff, the world does not revolve around you and your department, especially when a man's son is dead. He's got more on his plate than he can handle, already.

The urgency of the moment, the quantity of adrenaline in the Dad, the love of a father ... the cop's an @$$hole for not allowing this superman to do the job ... at least help.

Dad will spend the rest of his life muttering to himself .. "I could have done it ... I could have done it ... "

“No jury will convict him.”

They don’t WANT it to get that far. Just shake him down for a fine and some involuntary servitude (”community service”) in exchange for clearing his record.
That’s modern American “justice”!/s
