You change the gun laws, you punish the innocent.
You change the 14th Amendment to exclude children born to illegals, you punish the criminal.
You punish the child not the parents.
And it would not curb any type of illegal immigration. It will just create a 3 day waiting period to check the backround of the parents before a birth certificate is issued.
That's going to be fairly easy to get around, don't ya think?
