Most School Shooters Use Guns Taken from Home
Most school shooters are suicidal before they attack. American children are ten times more likely to commit suicide with a gun than by any other means. More than two thirds of school shooters take their weapons from their own home, making it extremely easy to carry out their plan to kill others before killing themselves. So, owning a gun not only can make the families of suicidal children unsafe, but it also may place their children's peers and teachers at risk of death or injury by firearms.
The combination of a gun in the home and a depressed and/or suicidal child increases the risk of death exponentially. It is not uncommon for teens to experience depression and sometimes suicidal thoughts. Also, teens commonly experiment with alcohol and drugs, and resulting intoxication increases the chances that a dispute will escalate into a violent confrontation. The presence of a gun in the home increases the likelihood of serious injury or death in these situations.

which is why we need to have a safe w/ a code lock or a triger lock for our guns
The most violent, tragic school tragedy in American History was the Bath School Disaster of 1927. 45 were killed and 58 wounded, most of which were children younger than 6th grade.
It was perpetrated by Andrew Kehoe, A school board member who was upset over a property tax increase. He used a series of explosions to carry out his deadly deed.
Don't talk about ease of committing terrible atrocities without reviewing, mourning, and respecting the most tragic one of its kind to occur in our nation. Do not imply that the tragic events of school shootings are limited to teen perpetrators- that is false. Do not say teens commonly experiment with drugs and alcohol, and then making a suggestive statement like teens often think of suicide.
Those things may all be true- but are not all true of each other. Your mixing a series of different studies from different samples and presenting a picture that is not representative of American Culture.
Of course the presence of a gun would increase the likelihood of injury in those circumstances- your talking about a suicidal, homicidal, drug addicted, intoxicated, mentally unstable, depressed person. The presence of a shoe string would increase that person's likelihood of injury.
your taking the most extreme, hypothetical, deranged situation- stripping inconvenient facts- and trying to present it as some form of reality. thats not debating- its generating a fiction.
