If you carve up the public sentiment...there’s three problems. You have the crazies/Somalians on a mob-like frenzy. Then you have the urbanites of Minneapolis who are in a state of fear that things are out of control. Then you have the remainder of the state...pointing out that the Governor/mayor-of-Minneapolis have no ability to ensure public safety.
I would suggest the FBI agents coming in...have no connection to the public safety issue, and mostly there to complete (in rapid fashion) gathering of evidence on fraud/money issues.
As for public safety...I expect by Monday night some type of curfew to go into effect.
