Question(s) about PA Police Academies?

I'm looking to become a local cop in my area, but I have a bit of a dilemma. Does anyone know if you need a 2 year Bachelor's Degree to become a Municipal Cop? A friend of mine that graduated the academy said that you need one for the State Police, but failed to mention Municipal Police. And I wonder why you would need to get a BD to be a local cop when they give you 16 credits towards a criminal justice program in collage and my friend is already a cop and he graduated the academy about 2 months ago. Anyhow, does anyone know if I need a BD or not?
