TWO SETS OF RULES: David Gregory walks free while Iraq vet was jailed.

It’s been more than a week since police in Washington, D.C., opened an investigation into NBC’s David Gregory’s possession of a “high-capacity magazine” that’s prohibited in the District on on national TV. Metropolitan Police Chief Cathy L. Lanier’s spokesman refused Monday to respond to whether Mr. Gregory had even been interviewed yet. This is a rather curious departure for a city that has been ruthless in enforcing this particular firearms statute against law-abiding citizens who made an honest mistake.

In July, The Washington Times highlighted the plight of former Army Spc. Adam Meckler, who was arrested and jailed for having a few long-forgotten rounds of ordinary ammunition — but no gun — in his backpack in Washington. Mr. Meckler, a veteran of the wars in Afghanistan and Iraq, says he had no idea it was illegal to possess unregistered ammunition in the city. He violated the same section of D.C. law as Mr. Gregory allegedly did, and both offenses carry the same maximum penalty of a $1,000 fine and a year in jail.

Mr. Meckler was charged with the crime and was forced to accept a plea deal to avoid the cost and time of a protracted legal fight.

Gregory has juice. In the Obama era, it’s all about having juice.
