For police officers to enforce the law, how much time must they study in law school?

Why is it that we give a cl of professionals so much authority of the lives and liberties of citizens with less legal education than some attorneys who fill out repetitive paperwork? Doing wills, trademarks, trusts and articles of incorporation really doesn’t take a lot of real intelligence once you’ve worked your way through a couple. Many people without law degrees do them for themselves, yet to do it professionally takes a law license. Work which has life and death consequences, not to mention the power over people’s basic human and civil rights is trusted to people who likely couldn’t even get into law school. Why is this? Should police be required to spend more time learning about civil rights than how to kill people?
