No it doesn't and its not nearly as doom and gloom as you think.
Yes, there is a problem when the oversight committee assigned to oversee an intelligence agency gets hacked by that same intelligence agency and files removed.
That however does not warrant the agency's destruction. Punishment and enforcement of law to maintain the heirarchy of oversight is what is called for.
Do we dissolve the military when they screw up? Did we disband the NYPD after they choked a guy to death?
No. Beacuse they still serve an important function.
The same goes for the CIA: the fact that the oversight committee is toothless and the agency itself is really the one in charge when no one is looking is reason to bring the hammer down, but not reason to give up on their mission. Lock up the guys responsible, fire individuals who would violate their oath of service, who owe allegiance to agency first and country second, and get on with the real mission.
