Such a supervisory committee/jury could NOT gain power long term. They should be well paid but severely sentenced if the least bit of corruption was discovered. etc. etc.

President Trump: Promises Made.....Promises Kept
ISO9000 system: Say what you do...Do what you say...and have it verified by independent audit.
