Illegal is the key part, he should have never have been here. The papers just don't want to offend the racist latinos and illegal alien lover lobby. But, I don't mind offending them.
If I were an LEO, and I witnessed a perp murder someone, I'd 'forget' the Miranda-PC BS, and put the perp away. And, actually I used to be sort of a pacifist in terms of the legal-judical system. After seeing years of mis-behavior, I'm fed up. Especially after 9-11.
