Mass shooters exploited gun laws, loopholes before carnage

              A solemn group of King Soopers employees, left, some from the Boulder store and some from the same district brought large sprays of flowers for each of the victims of a mass shooting at a Boulder Kings Soopers store on Monday. Each spray had a card with condolences for the victims' families and signed by their King Sooper family. The group brought their flowers to a fence around the King Soopers where a makeshift memorial has been made for the ten victims of a mass shooting. Tuesday, March 23, 2021.

The suspects in the most recent shooting sprees found it relatively easy to get their guns.
