Does the US have too many police officers?

It is hard to walk out one's door, go to work, go shopping, visit a friend etc., and you may run into scores of police officers both seen, and unseen. Are there too many? Is the US going bankrupt paying for "security" which is often a tool of citizen abuse? Excerpt from Wikipedia:
