Leave David Gregory alone!

Was it a stunt? Yep, and an eye-catching one. Was Gregory being aggressive with the NRA chief, or seeming to push gun control in a confrontational interview? All that is up for debate.

But a police probe over what I assume was an empty ammo clip is a total waste of time. What it demonstrates above all is that journalists are getting ensnared in the political war over gun control.

Even more absurd than a criminal inquiry into David Gregory is an effort by pro-gun enthusiasts to kick Piers Morgan out of the country. His crime? Carrying on a passionate crusade for gun control.
