From what I have been told much of the problem of straw buying is that the prosecutors consistently allow them to plea bargain down to minor offenses (even down to misdemeanors) which don’t restrict their future right to buy a gun.
Rather defeats the purpose of the law now doesn’t it?
So how do we deal with straw purchases? We enforce the laws properly that already exist.
This statement makes me doubt the whole article. The serial number is generally stamped in a part of the gun that is steel. Even if you file it off, they can use acid to raise the S/N again. There is a way to permanently destroy the S/N, but I'm not going to post it here. It definitely isn't with a screwdriver. You might be able to scratch over it, but it would take HOURS to remove it, and even then it's not going to be completely gone.
