An Associate’s degree in Criminal Justice

Should a police officer be required to have at least an Associate’s degree in Criminal Justice or some other closely related field?
Your discussion should include Does an officer's education level play a role in his/her ability to understand and protect the rights of defendants/suspect, does a typical officer without a C.J. degree receive enough training on Constitutional rights from a police academy, is there any research being done in this area, and conclude with your opinion on requirements should be required for one to become a police officer.
