It’s not like even with a clearance you can walk in and see everything do anything.
Right, clearance or not you can have ALL access terminated.
The get to the information, you must have all three:
1. Clearance
2. You must be listed on the access list for any given repository of classified info.
3. Even if you have clearance and you are on the access list, you still get nothing unless a need-to-know can be documented.
“Its not like even with a clearance you can walk in and see everything do anything.”
True, but having your clearance revoked is a big deal. Having a dormant clearance is still a major asset when looking for a job. Having a revoked clearance for cause makes it hard to find a job.
