Washington Metropolitan Police Chief Cathy L. Lanier seems to think that gun-control laws don’t apply to the liberal elite. The police chief helped Sen. Dianne Feinstein acquire “assault weapons,” which are illegal to possess in the District, for a news conference early this year to promote a ban on these firearms, then tried to cover up the police involvement.

Now, a response to a Freedom of Information Act (FOIA) request reveals Chief Lanier’s shocking willingness to bend the rules for partisan and ideological purposes.

Feinstein wants guns

Lobbyist Chuck DeWitt emailed Chief Lanier on Christmas Eve last year. “Sen. Feinstein has asked us to bring examples of assault weapons used in the worst incidents over the past few years.” The CEO of the Lafayette Group told the chief that the guns would be put on display at a media event and asked, “Could you put me in touch with your person who would have any of these weapons?” Chief Lanier’s response was not turned over.

However, a week after Mr. DeWitt’s request, Mrs. Feinstein’s press secretary, Tom Mentzer, asked the commander of the police department’s Crime Scene Investigation Division, Keith Williams, for 10 specific firearm models used in high-profile mass shootings, including a Bushmaster XM-15, Tec-9 handgun, Smith & Wesson M&P15 and a Glock 19 with a “high-capacity magazine.”

Since Cmdr. Williams did not have all the firearms the senator sought, Mr. DeWitt asked Philadelphia police to provide the missing ones, which meant bringing “the P15 and the Glock extended magazine” to Washington.

All of these firearms are illegal in the city — even on federal property — owing to the District’s law banning rifles with a detachable magazine and such features as a pistol grip or folding stock and all firearms with a magazines capacity of more than 10 rounds.
