Science disagrees. Many attempts are impulsive and a minor hurdle can be enough to stop them.
If anything this event further radicalized me into the gun control argument. I have shot a few and they’re fun and all, but at the end of the day it’s impossible to detach the form from the function. They are killing machines. Something as powerful as a firearm should absolutely have a regular psychiatric evaluation attached to it if you insist on owning one.
