McThag had a good post about making the "no fly list" the "no buy list."
Cut and pasted:
It's not that we want terrorists to get hold of guns. It's that what we'd call a terrorist won't match what will be a terrorist by law.
So, how does this apply? Look, I'm going to make this fast because I've got a lawn to mow and only a few hours before the storms roll in again.
Politicians tend to aim for the low hanging fruit. They make some half arsed definition that may or may not have real world application. And those on the no fly list, a good number of them are on it because their ID got stolen after they traveled to a nation that was not as stringent with their security procedures with passports as the USA is.
Look at the AWB. You could still purchase an AR as long as it didn't have too many "scary" items attached. Look at the bullet button in California. It is already been bypassed.
The law is a scary thing when it is drafted incompetently.
