I don't know if you were responding to me or the article in general.
If a criminal has no concept of "law" and obtains a gun - which is the MAIN argument by the NRA, do you think a restriction on alcoholic consumption would have any effect on them?
Another argument made by the NRA is mental illness and the treatment for these diseases. Mood altering drugs impair perception (which is one reason why the mentally ill are supposedly prevented from getting guns).
Alcohol does too.
As a person with a CCP I know that
Criminals get guns and
Criminals don't care about restrictions on alcohol

That said, I don't believe the risk is worth it.
