As usual the story is crime... More time doesn't deter crime just like the death penalty doesn't deter murder. You have to change the conditions, fight poverty and other root causes. More policing, aggressive policing doesn't deter crime, if it did St. Louis would be the safest city in the nation instead of the most dangerous.
These aren't Republicans. These are Democrats, the party that is supposed to fight poverty and other root issues. Not only do they not fight poverty and other root issues, they always get a black face to wield the hammer so they can say, "See, it's not racist" or "We're not being oppressive" because some negro scared of losing his/her job or standing goes along. This keeps us in a position of having to fight our own.
