So my question remains... how was someone that was declared mentally unfit by at least 3 psychologists & suffering from a 'serious' mental illness, able to walk into a store & buy a gun that's capable of killing 10 people in a short time??!!

If you can't 'take responsibility' for your actions, or their consequences, WHY is it perfectly fine for you to have access to the weapon in the first place?

Thoughts & prayers are obviously easier to offer than courageous reform
