Did those air marshals who shot Rigoberto Alpizar the other day know he had a bomb? Of course not. How could they? But given the situation, they had to shoot him, rather than risk themselves and the bystanders getting suffused with supersonic carpet tacks. Of course, now we know ... no bomb, just a harmless nutcase.
So, I would say, even if Maye heard them claim to be cops, if they burst into his room with violence, he was still justified in opening up. Good shoot. Dead cop. No drugs. Wrong address. Mistakes happen. Better return to civilized police procedures!
Good verdict. Death row.
