In the days following the murder of George Floyd, demonstrations have erupted across the country.And many elected officials have made efforts to control protests by imposing curfews.Essential workers, like those who cook and deliver food, are exempt from the curfews, but they have been affected.Workers have been forced to travel through militarized streets to get to and from their jobs.And for food delivery workers, curfews are impossible, since they may be in transit as curfews take effect.Indeed, there is confusion with curfew enforcement: How are police to tell, at a glance, who is exempt from the rule?.The efficacy of curfews in curbing social unrest is unclear, and for people working, it's just plain confusing
