This is why I did this last spring.

I’ll admit it, my entire goal this evening was to get my friend Piers Morgan to admit the truth, which is that he’d prefer to see magazine capacity limited to zero. He answered my question. It’s a question about which many have wondered: “where do you draw the line?”

[…]

Morgan says high capacity magazines should be banned to prevent massive loss of life. Obviously 26 lives lost is heinous, but are ten lives lost OK? Ten rounds was the limit under the ban enacted in 1994 (after which Colombine occurred). Some governors say now only seven rounds are acceptable. So are seven lives lost acceptable to Piers? By falsely tying saving lives to the number of rounds allowed in a magazine Morgan inadvertently answered that he would prefer zero rounds in the chamber, using his logic and the standard of measurement he himself established.
