LA is also very large geographically. Not exactly Manhattan 38 locations have reported rioting. There are some CHP and SO also so hard to tell how many on duty
The entire force should be on 12 hour shifts, but better yet where is the guard?
If they're outgunned or if this has reached such an absurd level then yes, ask for help. And yes, where is the NG?
But on some level, you have to ask...if all 9000+ police are on duty, and if they've had hours to plan and get intelligence and amass ordnance, and they're asking for the NG before it's dark...when this is all said and done some heads should roll.
