Felony rioting is the charge I read.
As for costs, transport costs are nothing compared to incarceration costs. Food, lodging, health care, cable tv, fitness club, free college education, appeals by public defenders , ect....
There are private prisons for a reason, money. (No one builds or runs one for the fun of it.)
I don't have the figures handy, but i remember i could have a nice vacation on the per day costs of holding one prisoner.
