This last incident has me scratching my head. How can someone jump a fence, sprint to the front door of the executive mansion before being apprehended? Another incident occurred in 2011, where a gunman pointed his semiautomatic rifle out of the passenger window late at night, and aimed directly at the home of the president of the United States and pulled the trigger. A bullet smashed a window on the second floor, just steps from the first family’s formal living room. Four days after the situation, the Secret Service finally realized that shots had hit the White House residence, because a housekeeper noticed broken glass and a chunk of cement on the floor.
