Having over 44 years of experience in the field (30 as a police officer/homicide detective and 14 in related law enforcement fields) the best advice I can give you and/or anyone else who asks what type of education they need for the field, I say this. Take classes and pursue a degree in a completely UNRELATED field, for a couple reasons. The police academy will teach you all of the basics to become a police officer. But what happens if you become injured, or if after a few years you find out this isn't for you? Now what? If you have that additional outside education, you're set! You may also be able to use it for side jobs as a police officer! I also recommend becoming a RESERVE police officer first if you have ANY doubt. That way you get a taste to see if it is for you, before you make that full commitment. And as a reserve officer, you would be a preferred candidate for a full-time position if/when you make that decision.
Good luck Josiah and if you make that decision to join the 'Blue Thunder,' then welcome to the family!
