Well, bottom line, is if your running from cops and then have an exchange with them, ya better take off immediately and keep moving...
Otherwise you're done...
I'd bet a cup of coffee Dorner fully understands this.
Also, they've got 3 mountain roads coming away from Big Bear that are now jammed bumper to bumper with thousands of vehicles as they search each one....Night fall is coming, and it will get below freezing....
What then?
