Clearly no one sane does this so of course these shooters are mentally unstable, that’s obvious. However, difference in America is the ease of access to guns and military style weapons, especially. How we can protect some ancient ‘right’ to allow citizens to hunt or keep a forearm for their self defense while reducing the production and access to assault weapons is what we urgently need to address…together. Unfortunately we haven’t done anything when children get assassinated so I’ve lost hope this or the next one will move the needle.
