Nothin like a criminal justice system that can try you again if they don’t like how things turn out.
How about charging him under federal codes for violations of (Steinle’s) civil rights?
He’s being charged on federal law violations, esp. as a convicted felon and a deportee. Nothing there conflicts with the state’s deliberately bungled prosecution.
You want this bastard walking the streets of any city? You’re the one who’s sick and dangerous, more than he is.
Hopefully his previous felony conviction will result in a greater sentence than if he had not been a felon. he’s a threat to society as long as he’s alive.
