They should get a small bucket truk from PG&E or phone company and put it on the other side of the wall and put a marksman in the bucket. Should be a pretty clean shot from 10-15 feet like that.
Take him out before he offs the others in the van.
Have they confirmed that someone else is in the van?
Those CHP officers have AR15s in their car...they can take him out whenever they want....
Now calling out LASD SWAT....
this will take all day!
