Get in shape, SRT kicks ass! NM you have a family...
Often times regular PD requirements are fairly lax, my uncle was chasing a suspect through some backyards, and the officer behind him (way behind him) was a fairly "large" man, and he fell through a pool cover that everyone else got over fine. But I would still get in shape while you still have a job, and check out your "Criminal Justice" opportunities as soon as possible, there is an officer on here. Your goal is to QUIT your current job because you'll have a new one...not to wait till Dec. 31st...
