Police dog unleashed on innocent children and a handcuffed man... What should happen to the officer?

If this story is accurate I think the police officer should be reprimanded. If the person was already restrained and he released a dog on it which obviously can't tell the difference between children and a restrained man, then someone needs to learn some restraint and common sense. I think certain law enforcement agencies (not all) are given way too much power and way too little training. Having a badge and 60 hours from a community college or some experience in the military might not cut it. Maybe stiffer requirements should be required of all officers, like, hmmm, maybe a minimum of a bachelor's degree and 1 year of training??
