“Let’s create a list to which we’ll add people that we suspect might be terrorists and then deny people the ability to travel on airlines if they’re on the list. They won’t be informed when their name is put on the list, and the method of removing their name will be harder than pulling teeth.”

“I love it! It will protect us from them terrorists! FUND IT!”

“And since the only people who are going to be on this list are terrorists or those we suspect are terrorists, why not bar those same people from buying firearms?”

“NO WAY! This list is prone to mistakes, people don’t know about their name being on it until they’re denied entry on an airplane, and it’s too difficult to challenge your placement on the list! We can’t deny firearm sales based upon such a list!”
