I want to know if I was accepted to train to become a sheriff would I have to live at the academy until I graduate or would it be like school come early leave late?
Depends on the Academy. Some larger departments, like the LA County Sheriff for example, run their own in-house academies, which are often live-in. Many smaller departments only hire people who've already got their certificate, and you 'can' get that through Monday-Friday classes at your local community college.
