It’s not a foolproof plan, but here’s a creative, only-in-D.C. way to scare off a would-be mugger.

Apparently a 95-pound woman scared off a man who was trying to rob her around the Capitol Hill/Union Station area Monday evening by telling him that she was an intern for the National Security Agency and if he stole her cell phone, which was in a Lilly Pulitzer case, the NSA would probably track it, according to the Washington Examiner.

The Examiner reports the victim was walking home to her Capitol Hill townhouse when a man “violently confronted” her and demanded for her to hand over her wallet and cash. The woman, who actually works at a nonprofit and did have cash on her, told the man that because she was just an intern, she had no cash, and then went on to elaborate that it probably wasn’t in the mugger’s best interest to take her phone.

“I told him that the NSA could track the phone within minutes, and it could cause possible problems for him,” the woman, who asked to remain anonymous, told the Examiner.

And that seemed to do the trick. (The Metropolitan Police Department couldn’t find any information about the robbery when City Desk inquired; Examiner reporter Tim Mak says the victim did not report it to the cops.)

It’s unclear if the robber was armed. But it’s safe to say you probably shouldn’t try this tactic yourself.
