I know it's racist to say this, but my habit, absent other evidence, is not to blame conspiracy when stupidity is an entirely adequate explanation. from what I've heard, the two Secret Service agent went drinking, got called to the scene of some sort of incident, and instead of saying, "I can't, I'm drunk," went to the scene of the incident and crashed into a barrier there. IOW, they got drunk while "on call" and drove to a call while impaired - stupidity, not racism.
