Men and women are 29% likelier to die in a gun homicide. America has the highest rate of gun ownership than any other country.

These may not seem like large numbers, when in fact the number of people dying in the country should be 0.

There was a 20 year old man under the name of Adam Lanza, he killed 20 children and 6 adult staff members.This was the highest mass shooting in a school ever recorded in the USA. The reason Adam started the shooting was because him and his mom had a fight, due to this Adam was mad and wanted to give revenge. His idea of revenge was to shoot kids in the school his mom worked in. If the Adam or his family had not owned a gun or had not given him one, there would not have 20 innocent children dead.
