Kid if the killer cop was the best they have then that police force is the dregs of society...
Who said he was the best? Even in the medical field, someone has to graduate last. And they did make a big to do about him being the first somali on the force.
Society has demanded diversity and the police departments are striving for that. However, after Ferguson, many of the best and brightest are not considering a career in law enforcement so we work with what we have to maintain basic police service.
