I do not recall the source, but I recall looking into this very thing back in the 90s.
IIRC, a DA attempted to prosecute a criminal who lied on a 4473 form.
The judge threw it out because he said of course the man lied - he's a criminal and therefor the law did not apply to him. Or words to that effect.
This may be an urban legend, but that is what I recall.

To our Lt. Governor and others: Lets make it a point to prosecute those who lie on a 4473 attempting to illegally buy firearms. Let's do that before we start limiting the rights of honest people.
