DEA is just an extension of the C_A. They make sure that no one ever really gets caught. If someone does get caught it is used as an example. At the very exact moment most likely 10x that amount is being let through courtesy of the C_A via DEA.
Ask yourself why the NTSB was NOT sent to Ketron Island to investigate. They are dirty as well. NOt every single person but enough of it's leadership is comped so it is directed to 'investigate'. Of course those investigations never come up with anything other than 'pilot error' or 'weather issues'.
Remember the stats 7/10. Controlled crashes. Can do that fairly easy if the NTSB has your back.
