"80% of guns used in mass killings were obtained legally."
But NOT possessed legally- the various mental conditions, per the law, are to be reported, and they were NOT acted upon- in violation of the law- So, are those guns "legally obtained"?
" The same goes for domestic killings, accidental or intended."
And are those killings legal or illegal? IF used for self-defense, or to prevent a crime, I would HOPE that they had been obtained legally.
What percentage of the guns USED IN ILLEGAL ACTS were obtained legally? THAT is the figure that you might use for this discussion.
MOST guns are legal, and NEVER used for an illegal act- yet the anti-gun nuts lump them all together
