I've been training a new officer at my agency. Seems OK, a little nervous but that is what training is for.
My only complaint? Keys. The key ring only has a limited amount of keys on it. If you do not know which key opens a door, try all of them. IN ORDER! Don't pick one random key, then another random key, then on and on. You will never find the key. If you start with one key and work your way through then you will have tried all the keys. And one will work!
