The deputy is dead because a dirty maggot decided to live a criminal lifestyle. Shouldn't have had five pounds of pot and guns in his house. Hopefully he goes away for a long time on those charges.
Well yeh, but if they had knocked loudly and announced, "Police!" the guy might not have thought it was other criminals breaking in for his stash. If they just go around kicking in people's doors late at night even with no knock warrants, it scares folks. People don't know it's the Police kicking in their door. I mean, they can keep doing it if they want to, but it's not a real safe thing to do.
