New York Mayor Michael Bloomberg was in town Thursday to support Cincinnati Mayor Mark Mallory and 12 other mayors from Ohio and Kentucky who want to track gun sales and let law enforcement use the information to catch criminals.

Cincinnati is leveraging its influence nationally, and is promoting regional collaboration on the important issue of illegal gun purchases.

Bloomberg and the mayor of Boston created the national Mayors Against Illegal Guns coalition, which is lobbying to repeal a rider in the next appropriations bill that restricts access to gun ownership data.

Some may decry the effort as anti-Second Amendment, but it's no such thing. Rescinding the so-called "Tiahrt Amendments" would simply allow local law enforcement to trace federal gun-purchasing data, and more quickly solve gun crimes.
