No, most likely you are not out $2000.
BUT, you probably won't have a leg to stand on with ANY insurance company unless a police report is filed. Do you think that an insurance company is just going to take your word, without any report/complaint filed with the police, and simply hand you $2000? Heck no! I could easily call up my insurance company and say someone stole my car, but they aren't going to give me a dime unless the police are involved and can back up my story.
Here's what you need to do:
1. Gather together all the witnesses, parents, friends, etc. and call the police.
2. Have each person tell what they saw, overheard, did, etc. to the police.
3. Have the receipt for the MBP to prove you actually bought it, and furnish a copy of it and the serial number to the police.
4. Call YOUR and YOUR FRIEND'S home owners insurance companies to report the theft. They can work out who will be paying (if the MBP is not recovered).
5. CALM DOWN! Take a few deep breaths, take a run, do anything to blow off your stress. It WILL BE o.k.
Just CALL THE COPS!
