Cheating death and fighting communism: that is how a fellow officer once described our job.  It was meant to be funny, but as time went on it seemed all too true.
I spent more than ten years in law enforcement, all of it on the street in uniform patrol.  I've been a patrol officer, instructor, sergeant and lieutenant. 
Do not report crimes here. Nothing here should be considered legal advice. All opinions are my own.
Call the police.
This is a good starting point: http://www.sjpd.org/BFO/FieldTraining/home.html
Sounds like you are in a bad spot. However, if you are unwilling to call the local police for assistance, I don't know what you expect anyone else to do.
                             Officers are trained to protect the public.  Each incident is differerent, and the risk to the public could be greater by allowing him to leave the restaurant.  For example, what if he is parked by the front door and has a bomb in the vehicle?  It might be safer to take him down inside.
There is no way to control a situation and completely protect the public.  That is an unrealistic, but common, view.  Officers will take reasonable actions based on the information they have at the time.

                              It might. You should contact the California POST: http://www.post.ca.gov/
I'd suggest contacting a family law attorney in your state.
                             You can spend a lot of money at a "top rate" university, but it won't help you become a police officer any more than going to a regular state university.  It will help you get deeper in debt, though.
If your desire is to go to a college, please do so.  If your desire is to be a police officer, consider entering military service, getting some life experience and a skill.  Read through my prior answers on this above.
Best of luck.
