white house grounds where president obama lives. in march last year, a man climbed the white house fence in broad daylight. got arrested. later that summer, it was a toddler who didn't jump the fence but was able to slide right through it. later that month, a guy jumped across the fence, ran across the north lawn then ran inside the white house. the man was armed with a life. he made it through the north port co doors, was well into the interior of the ground floor of the white house before he was finally taken down by a secret service agent who had finished his shift and was on his way home for the night. it was after that that the secret service decided yeah, there's a lot of things wrong here, but maybe the white house fence itself could give us a little more help in stopping these things f s from happening. after the last incident, the secret service and the park service installed these temporary bike racks around the white house fence to try to deter people from getting near it, maybe?
