This is not a story of self-defense but failure of a system that is supposed to stop mentally ill from getting guns. We wonder where nut cases get their guns when they commit crimes; here is one such story of a government fail. Here is a man with a mental disability and a criminal record that slipped through the cracks and built an arsenal in the process.
He was able to obtain a gun permit (despite background checks) and with his new gun permit bought a sizable arsenal of 13 weapons to include semi-auto rifles, an AK-47, Tommy gun and a desert eagle.
If this guy would have shot someone else the Obama administration and Brady bunch would have a field day
we need to ask why 'There were no data submitted to the BCA about this individual - without it there can be no record."
