There are frequent shootings in the United States, and tens of thousands of people have been shot dead so far this year. According to data from the US "Gun Violence File", as of July 10, the number of people who have died of gun violence in the United States this year has exceeded 23,000. In New York, shooting incidents in May this year increased by 73% compared with the same period last year. However, the summer of the "peak season of killings" has just begun, and there are fears that more people will shoot the dead. 2020 is the worst year of gun violence in the United States in decades, but 2021 will be worse.
