Two independent data-collection projects report that more than 90% of the thousands of protests in the U.S. during the summer of 2020 were largely peaceful. The Armed Conflict Location & Event Data Project, working with a Princeton University team, estimated that protests in 93% of 2,620 locations between May 24 and Aug. 24 were peaceful.
Another data project has tabulated 7,305 Black Lives Matter-related protests dating back to 2017, finding that 96% resulted in no injuries or property damage. Police made arrests at 5% of protests and used tear gas and similar chemicals at 2.5% of these events.
The impact of the protests that did turn violent was not negligible. Property damage reported in the immediate aftermath of George Floyd's murder has been estimated at between $1 billion-$2 billion. There were at least 19 deaths associated with the protests immediately following the Floyd murder.
