"This is America. We need to have this debate," Martin said. "If you want to make a decision that 5,000 people can die because you don't want to make a bad guy feel uncomfortable, that's a decision we have. But then, you bear that responsibility, and you'll look in those victims' relatives' eyes after the fact. But the fact is, that debate and that discussion needs to occur, and we live in a free society where that needs to happen."
Martin said he believes such methods have saved hundreds of thousands of lives.
