Guns used 2.5 million times a year in self-defense. Law-abiding citizens use guns to defend themselves against criminals as many as 2.5 million times every year -- or about 6,850 times a day. This means that each year, firearms are used more than 80 times more often to protect the lives of honest citizens than to take lives.
Of the 2.5 million times citizens use their guns to defend themselves every year, the overwhelming majority merely brandish their gun or fire a warning shot to scare off their attackers. Less than 8% of the time, a citizen will kill or wound his/her attacker.
