What is Up with the Secret Service?

What in the world is going on with the Secret Service? A loner goes across the White House lawn and into the East Room before finally being stopped by an off duty agent. A couple schmoozes their way into an Inauguration party and gets a picture with the President. The President rides an elevator with an armed man who has 3 - count 'em - 3 felony convictions. And how about the drunk agents staggering around Colombia in 2012? Whoever is President deserves the absolute best protection and that simply isn't happening.  It had better get squared away now before a jihadist hit team with real operators decides to take a crack at it.
