It seems as if there are around 270,000,000 firearms of various descriptions, privately owned in the USA…. statistics vary, probably because no-one knows the exact number.
Around 6% of the population suffer from ‘serious mental illness’.
Therefore, around 16,200,000 firearms are in the hands of the mentally unstable….
…and it is your “right to bear arms” ..?
Well, good luck with that……
