White House Related Robberies a Coincidence?

First this:
"[A]cting White House Travel Office Director Gregg Pitts was beaten and robbed by at least two men while out in Honolulu Monday night. Pitts suffered head and other injuries in the attack. He was awake and alert but remained behind at a Honolulu hospital because of a possible concussion, White House spokesman Tony Fratto said."

Then:
First Daughter Barbara Bush had her purse and cell phone stolen as she had dinner in a restaurant in Buenos Aires, Argentina, even though she was being guarded by a detail of Secret Service agents, according to law enforcement reports made available to ABC News.

It was not the only mishap on the two-week trip to Argentina by Barbara and her twin sister Jenna.

A Secret Service agent on the advance detail got into an "altercation" with someone after a night out and was badly beaten, according to the law enforcement reports. The Secret Service said today the incident was an attempted mugging that occurred while the agent was on his own time. The agent is doing fine.

Either these incidents have nothing to do with one another, or something is afoot. Perhaps someone is looking for something? Conspiracy theorists could have a field day with this one.
