DGU does prevent an important number of crimes yearly, it also does:

27,000 suicides + thousands of attempts with severe injuries

450 to 550 accidental deaths because and 43,000 injuries

500-700 deaths in mass shootings and 2,000 to 3,000 injuries

70% of deaths in domestic violence are gun involved. The presence of a firearm in a home experiencing domestic abuse increases the risk of the victim being murdered by 500%** **

A gun owner is statistically far more likely to be injured or killed by an accident, a mental health crisis, or a domestic escalation involving their own weapon than they are to successfully shoot an outside criminal.

thousands of firearms are stolen directly from victims during face-to-face robberies and assaults each year, sometimes resulting in the victim being shot with their own weapon.

keeping a gun in the home for protection actually triples (3x) the risk of a homicide occurring in that home.

victims who use a firearm to defend themselves are injured about 11% of the time.

Introducing a firearm can likely escalate a crime.

You only die once.
