Secret Service director resigns after security lapses

[Botany]

2. What took so long?

What should be one of the most protected buildings in the world had somebody
jump it's fence, run more then 50 yds to the front door, go into an unlocked door,
overpower the guard at the door, get into and run around the building because
the alarms were turned off, and was caught because an off duty secret service
agent just happened to be there.

BTW what still gets me where were the guard dogs? Because incidents like this
one is exactly why the have such guard dogs ..... overwhelming non lethal force
and if the person has a gun or a bomb then the dog gets it and not a human.
