As controversial as this may be- we should have ONE new law regarding guns/criminals- they should know that they can't purchase a gun (got this idea from Penn Jillette), if you're a felon and you attempt to purchase a firearm (not just denied for whatever reason, because my brother has been denied in the past and then cleared it up and could buy), you shouldn't be told 'no' then be allowed to just walk away. I'm not a lawyer or legislator, so I'm not sure what you could punish them with, but I'd say something to the effect of community service and/or probation or something.
