Ok here is what I would do.
First, film him in the act a couple of nights. This gives your proof and sets up your AFV winning video along with the video you will send into the local News Station.
Find a police officer you know or one that one of your friends know and bring him into the loop. If you can make a case, ask if you can make a sting operation to catch him. If you don’t have a case, ask if you could at least get their help to teach him a lesson.
Now ill take Babalonian's second plan for use and tweak it.
You will need:
*Three friends, a couple of cops in police cars, a van, multiple cameras and robbers costumes and a baseball bat/fake gun or real one (unloaded) and hammer?
Setup: place the cameras around your property so you can capture multiple views of the act. Have the van sitting right by your house from late afternoon on until the sting but make sure it is out of direct site of your neighbors house so the get-away driver can get to it without being seen. Find out what time he comes at so you know when to start preparing for the sting. An hour before the sting, have the police officer in the patrol car arrive nearby out of sight but in direct site of the van.
The plan:
Get someone to do your routine for you. You and three friends will “Rob” your house while he is on your porch.
One friend will be in the van as the get-away driver sitting waiting. After your neighbor enters your yard, you and your friends will go out and enter behind him acting like your about to rob the place. As soon as you guys start in, the driver will start the van and start creeping up. When he sees you guys, you turn and run and jump in the van and speed off. Mean while when the van starts the police officers also start their cars and follow up. Just as the van leaves your house the cops should turn on the lights and pull up to your house and “arrest” your neighbor. If you want to actually press charges (if you have a case) then they can actually haul him in. If not, then they can just hackle him for a bit then let him go.
Meanwhile, you have the film of all of this, so you make a very good video of it. Send it in to America’s funniest home videos and also to your local news station. Hopefully the news station will run it and make a big deal out of it…
Oh and remember to put it on Youtube and post it here
