So it's acceptable that someone who has serious mental health problems, as you suspect the shooter does, to be able to get their hands on a gun ?
Speaking from a British point of view l am so happy to live in a country where we can send our kids to school KNOWING that they won't be shot . Or that l can pop to the shops , which is where the last mass shooting occurred, and KNOW that l won't be killed by a schizophrenic with a legal gun
Or l won't be killed by a child playing with Pop's revolver because it's fun .
That is freedom.
