The ones who agree usually just nod in approval and move on. Recently, I wrote a column methodically debunking the claim that guns in the home are 43 times more likely to kill a family member or friend than an intruder. It actually drew an approving response from one letter writer who asked that I also address the assertion that 13 children are killed with guns every day. I'd be happy to. This is an old saw, oft repeated by anti-gun types and enthusiastically broadcast by the liberal media.
People have heard it so many times, most probably believe it's true.
As you might suspect, the statistic is contrived and distorted. It was last sighted in prominent statements by Bill and Hillary Clinton. It found that 4,205 personas up to and including the age of 19 were killed in that year in firearm-related fatalities. Divide that number by 365, and you get an average of 11.5 per day. Somehow, the Clintons rounded that up to 13.
