Four years in prison is a lot of taxpayer money you'd spend over this, several magnitudes more than the property damage they inflicted. I understand that you're making that calculation rationally, with the theory that this extremely harsh punishment would act as a deterrent to similar crimes. A lot of people would consider that to be outrageously disproportionate, and outrage generates publicity. These people who threw soup in the museum, weren't they hoping to become martyrs? Is there nobody who would imitate them and purposefully go to prison for a moment in the news?
