From memory; Murders by firearm and suicides by firearm are about the same percentage.
I realize things have got to be pretty rough for a person to take their own life, but I tend to get a bit angry with folks who use a gun.
I know two brothers who did this about 15 years apart. Both had families and both shot themselves in their homes. This leaves a horrible visual scene for their families to discover. One of the brothers laid out a sheet, sat down on it and shot himself in the head. He must have watched too much TV and thought he’d have just a tiny hole and maybe a pool of blood, but in reality, he did have a tiny little hole at the entrance and a huge gaping exit hole where it blew bone, skin and brain matter all over the walls for his family to clean up.
