Secret Service considers a larger buffer zone around the White House
After an unprecedented security breach Friday night at the White House, the U.S. Secret Service is weighing a series of measures that would move tourists and D.C. residents farther away from the complex to reduce the chances of intruders piercing its security perimeter and endangering the president.
One proposal is to keep people off the sidewalks around the White House fence and create several yards of additional barrier around the compound’s perimeter. Another is to screen visitors as far as a block away from the entrance gates.
