Another day/week/month goes by & DEA proves worthless
As more time slips by, the DEA proves itself ineffective and basically worthless. If they can't get it done on a very simple, basic, rubber-stamp situation like this, what good are they? God help them if they ever have to deal with a complicated situation.
Every day that goes by increases the DEAs liability. If they acted quickly and later realized they made a mistake, they could always blame the pressure to act quickly. But now that it has taken such an extended amount of time, they have no excuse and no escape. Dumb as a stump.
