I would find it hilarious is the assassin remained at large because people refused to snitch.
Also remember, things are newsworthy because they're novel. US sees like 2 gun deaths per day and thousands due to insurance company malpractice, but this one death dominates newscycles.
There are about 50,000 gun deaths in the US every year, same as vehicular deaths. About half the gun deaths are suicides. About none of the vehicle deaths are.
In 2023, the average number of people who died from gun violence in the United States each day was 118. This is based on the 43,163 people who died from gun-related injuries in 2023.
