‘Fearful and trigger happy’: flooded with guns and paranoia, the US reels from shootings

Permissive self-defense and gun laws spotlighted by recent shootings in which victims approached gunmen by mistake

Waldes Thomas and Diamond Darville were driving for the grocery delivery service Instacart near Miami in mid-April when they drove the order up to the wrong address.

Thomas, 19, and Darville, 18, reportedly told authorities they were backing away from the home when the owner emerged with his son, grabbed on to the driver's window and fired a gun three times at their car. Antonio Caccavale, who didn't hit anyone, later reportedly claimed to police who investigated the encounter that he shot because he feared for his and his son's lives as Thomas and Darville's car ran over his foot and struck a boulder.
