anti 1: According to the Center for Disease Control(CDC)
In the year 2007
Homicide with a firearm: 12,129 (33 a day)
Suicide with a firearm: 17,348 (47.5 a day)
Death by accidental discharge of firearm: 721 (just over 2 a day)
Homicide: This stat does not separate out lawful from unlawful homicide. Even so, there are an estimated 250 million firearms in the US, and even assuming that every firearm related homicide is caused by a unique actor, only one out of every 25,000 firearms is used to commit a homicide.
721 accidental firearm deaths means that pools, falling trees, and plastic buckets all have a higher accidental fatality rate than do firearms.
Each of the above firearm death statistics have one thing in common: people who misuse inanimate objects. It isn't the firearm, it is the person misusing it.
Anti 2: You're right, a person could kill another person however they'd want but it's easier with a gun. People are more inclined to do something if it's easier.
