Easily done. Simply declare that anyone arrested for any riot-related offense lose their EBT, their Section 8 housing and/or their federal student aid for at least a year. Anyone subsequently convicted should be cut off from taxpayer-financed subsidization for a period of not less than five years for misdemeanors and permanently for felonies.
This stuff would stop within the hour. An Executive Order should do it.
Damn it, I really need to be President, even if just for a day or two.
