Another week, another violent encounter prompted by a visitor to our fair city: Shortly after 2:30 p.m. Thursday, a woman identified as 34-year-old Connecticut resident Miriam Carey drove her black Infiniti sedan into a White House barricade. She was blocked by Secret Service but managed to evade them and proceed at high speed down Pennsylvania Avenue to the Capitol, where she encountered police on the west front. After an almost comical chase around the Capitol drives, Carey exited onto Constitution Avenue and a few blocks later crashed into a guard shack near Second Street NE. Police officers shot her dead there, then discovered that all the while, she had her 1-year-old daughter in the car. The first reports about Carey, a dental hygienist, “suggested a person unlikely to be found at the center of such violent drama.”
