Gun Free Zones are Self-Defense Free Zones!
What do these mass shootings have in common? They were locations that banned guns! Even the Fort Hood terrorist shooting took place on a "secure" military installation. The Portland mall shooting was mitigated by a citizen with a concealed weapon (the media didin't tell you that fact).
The goverenment can't even protect a few soldiers on a secure base, what makes you think the government can protect all of us all the time? It's impossible.
Citizens MUST retain the innate right to defend ourselves!
