All good information so far, "highdraglowspeed" nailed some god points. Pretty much you attitude, shown in both the way you conduct yourself and dress, will make the impression. It's called a ride along and it's just that. You aren't the cops backup or anything. Not saying that if he starts getting beat he will not appreciate you joining in. Don't show up wearing BDU pants, boots, duty bet, etc. MSP has a professional looking uniform and you should look the part. Even though you really don't represent the Dept. the public will look at you as if you do. MSP will appreciate the good image.
I don't know anything about Norwich U but assume you have military courtesy engraved into you by now. Use it at the station/HQ but don't overdo it with the officer you are with.
Also skip or at least don't dwell on firearms, pursuits, etc. Yeah that is the fun part of police work but there is much more. Ask all around questions.
If things go well with the person you are with get contact information and ask if you can use him as a reference in the futyre. Not a main reference as he dosen't know you that well but he can attest for you character especially if you apply at his department.
Good luck and lets us know how it went.
