If some scrubby looking person jumped over the fence surrounding the White House grounds, he or she would be arrested; as has happened quite often in the past. Yet, two party crashers, dressed in a tuxedo and an evening gown, did effectively the same thing as the scrubby looking person but were are allowed to go scott-free; appear on talk shows; and, will probably garner a book deal. Yet, in both cases, there was trespassing on White House grounds.
I guess the moral of the story is :
If you're going to jump over the White House fence, make sure you are dressed to the nines and, then, I guess the Secret Services and White House staff won't bother you. You might even get to meet Joe Biden and the President.
