How many times does this have to happen?
The shooter, a stupid kid, apparently well-raised, pursuing an education, from a stable family with a father who is in law enforcement. Imagine that.
How does this kid go as far as to assassinate anyone?
At the age of 22, he had no significant life experience. Is hard to imagine he had a well-formed political view, yet he was full of hate.
At age 22 I was working, studying, and chasing girls with no care in the world about politics. When did politics infiltrate the lives of young men ?
IMO any political or religious Activist who goes around to talk to young adults about their ideology should not be welcome in schools.
Let the kids make their choice and seek those activists outside of the school if they want to. Young adults ages 20-25 based on scientific studies, are still developing the ability to execute critical thinking and are still mentally maturing. They might not be idiots but they are impressionable.
I believe that if this kid goes to the electric chair because of what he did, the shooting problem will not go away.
Punish, intimidate, kill, and destroy is just going to make matters worse.
