The Secret Service is between a rock and a hard place. After too many mistakes that received quite a bit of press coverage it is not surprising that there was this poor judgement to shut down a park for security purposes.
Why was it poor judgement to shut down the park?
The shut down ended up shutting down "CureFest for Childhood Cancer." The rally had a permit and half the attendees were children. Many people ended up not being able to enter the park to just get items left behind.
Did anyone in the Secret Service take a moment and think that this might not be a good idea?
