>Why hire these idiots that can barely do police work.

Because that's what they're hired for. Police aren't meant to protect people or actually solve crimes, otherwise the government would be as concerned with these current problems as they were of "terrorism" or the "war" on drugs. If the government or people in charge are actually motivated or care about something, a lot can be done and has been done with previous issues. If nothing's being done, that tells me that it's simply not a problem they want to handle/fix.
