graduation party

I have been planning a party for Hot Fuzz's graduation. I met another wife on a forum that recently threw a party for her husband. She's been helping me with tons of ideas. It's pretty much going to be over the top and it will probably embarrass HF, but I come from a family that never celebrated ANYTHING, so I like to go above and beyond when we mark a milestone in our lives. Here's what I have so far (if anyone has any great party ideas, let me know):

1. Invitations: Look like a subpeona (my father-in-law is majorly paranoid and he'll probably think it's for real when he gets this in the mail)
2. Decorations: Police line tape, chalk outlines around the house (with tape instead of chalk of course), a line-up corner for mug shots. I'll have butcher paper or something to do the height measurements, and guests can write their names and a congratulatory note to HF on a small dry erase board to hold in their pictures. Blue and red police beacons?
3. Food: cake made to look like his department's badge, depending on the weather-a BBQ. I'm still working out the food and drink ideas. I think I've seen at party stores police themed plates and napkins.
4. Games: "Guess that Cop". Have on the wall 50 pictures of famous historical, fictional, and tv cops (John McClaine from Die Hard, 21-Jumpstreet, Barney Fife, Inspector Gadget, etc.) We'll see how many people can name. Also, a donut-eating contest or donut game. Funny but true laws. I can't believe some of the laws in my state.
5. Gifts/Party favors: handcuffs, police hats, police whistles, and badges for the kids or anyone else who might want them.

I need to figure out a nice graduation gift for him. I found something I thought was cool. It's called a Lock-Write. It's a pen and a cuff key! I don't know if he would actually use it, but maybe. I was also thinking about getting him a digital voice recorder with USB connectivity. He mentioned needing one of these. Does anyone have anything to say about those?

I can't believe all the equipment an officer has to get on his own without the assistance of the department!! It's a good thing cops get paid a million dollars, otherwise we wouldn't be able to afford it all.
