What is the shooter's mental history?
Was he a prohibited person?
What type of firearms did he use?
Was the location a 'gun free zone'?
before we make final judgements outside of it being a tragedy, anti-gun advocates are putting out press releases before the bodies are even cold. They don't know any details beyond that there was a shooting but they want politicians to 'act':
Gun violence is preventable. It is long past time for policymakers at all levels to act.How is it 'preventable'? Well they'll determine that later depending on whatever talking point they can get momentum on. 'Assault Weapon', 'Assault Clip', 'Gun Show Loophole', 'Terror Gap'. It doesn't matter as long as they can express their outrage first and trying to make themselves seem 'mainstream'. In reality, those 'over 30 organizations' consist of a few dozen people nationwide.
So who are the ones that really care about preventing violence and who are the ones playing politics w/ a tragedy?
