Negligence is a reasonable charge but I think this AG is looking for revenge and is overcharging which will lead to further unrest.
If the cops are found guilty of lesser charges, the city will riot. If the cops are told to stand down next time I BET THEY IGNORE THOSE ORDERS.
From her demeanor, I suspect she is motivated to go for the most serious charges she can and hope she get get enough evidence to convict. If that’s the case that is a very bad idea as it will result in massive riots, worse then Monday’s because she tried to score political points.
