“Although Mr. Bloomberg wants to ban “armor-piercing bullets,” he doesn’t seem to know much about them, either. First, nobody can get them legally for handguns except the police. Then the mayor claims that: “The only reason to have an armor-piercing bullet is to go through a bullet-resistant vest.” That is just not so. Rifles with standard ammunition often can penetrate such vests, because their bullets travel faster than those fired from handguns. Yet if the mayor had said that hunting rifles can penetrate these bullet-resistant vests, his comments wouldn’t have generated the same support. Mr. Bloomberg’s emotional responses are understandable. But facts matter. The mayor should take a private lesson from his police officers on gun basics.” – John Lott in today’s Wall Street Journal
