It was a mass trespass event with a handful of people causing destruction. Many people were invited in others got caught up in the hoopla of an event such as this and it was instigated by some bad actors. It was not a riot, it was not an insurrection. It was a large crowd that was mismanaged due to Pelosi intentionally not properly manning the area wit LEO and Guard.
How does that happen? Are people that easily enticed?
