What if this secret service thing was really a failed coup attempt?

What if what happened in Colombia was really a failed coup against the President of the United States? Not a coup within the Secret Service but an actual coup against the President. An attempt to somehow set him up for a fall. Maybe an attempt to involve him in some kind of illegal behavior which would then be observed and reported. It doesn't make sense to me that so many honorable men in such an honorable and important agency would be involved in something so unprofessional. These men would all have passed one or many lie detector tests during the course of their career. No matter what really happened it seems like the public is being spoon fed a cover up story. The real truth may never be known. I feel for those within the agency who are becoming scapegoats for the failed(?) operation.
