Cuz they knew her arrest would give investigators MUCH more leverage to get at the truth, truth that would bring down 1/3 or more of Congress, and maybe an ex-President and ex-candidate.
She had on her person an amount exceeding the minimum for arrest.
They deliberately sabotaged their investigative prospects, just has the director did on behalf of Hillary.
The FBI is an entity not only NOT doing it’s job, but SCARED to do so.
NOT having any FBI would be a step forward.
FAKE FBI is simply delaying the day that Americans actually get real protection.
A fairly standard part of busting up a spy-ring:
The main perp already knows he/she might be going away for life.
Their child or spouse? Their freedom is still at stake.
So the Feds will lunge even at scant chances of incriminating them —it provides muuuuch greater leverage over the arrested perp.
“Tell us what we want or junior/wifey joins you in Supermax...”
THAT’S why they let her go.
