It's an unfortunate aspect to our society, but whenever a crisis occurs bad actors come out of the woodwork to make situations - sometimes intentionally - worse.

Minneapolis Police Chief Medaria Arradondo spoke to the press on Thursday and was asked about reports of people from outside the city causing a significant portion of the damage.
