Sometimes a photo tells you all you need to know about a person: e.g., http://i.imgur.com/4CIFpFe.jpg . Modern American law enforcement: a gang of wannabe tinpot dictators with weapons they have no business with, and that they probably have no idea how to use.
That's an M1911. They're designed to be carried in condition one, which means that the hammer is cocked and the manual safety is engaged, otherwise known as "cocked and locked."
I don't know why you're getting down voted, maybe people don't know the first rule of gun safety: Always treat the firearm as if it is loaded. (which on the internet is "the gun is always loaded" shorthand.)
Yeah, stereotypically speaking, it's the 90% of bad cops that give the 10% a bad name. Funny, though, the "good" 10% don't seem to have a problem with that.
Finger off the trigger, Sheriff.
