if you gotta ask then you’re too old... I started at 28 almost 29 myself. I’ve been in going on 5 years now. Like most have stated getting in sooner would have been great especially on the retirement side but unless a dept has an age cap any age where you can safely meet the requirements of your duty station is a good age. I had a guy in my academy who had already been a state trooper for 20 years in a different state, took 5 years off couldn’t handle sitting at home so when he moved to Oklahoma he got back into LE. Only reason he had to go back and finish with another class was because he had a major family crisis that took him outta classes longer than he could be to successfully meet requirements, and while in DT he pulled something in his back. This man was HARD... and in his mid to late 60’s
