I honestly wouldn't reccommend going into law enforcement with a stutter, police officers have to do a lot of communicating with other officers and people they deal with in day to day. You have to have extremely strong speaking skills and also confidence in what you are speaking. There are lots of times you need to make phone calls to minors parents as they legally have to pick them up. If you think you can manage all those things then go for it but just be aware they turn down people who have very strong speaking skills they just aren't what they are looking for. Best of luck.
