Notwithstanding the claims of the low information posters, the FBI agents were ordered to not wear any identifying insignia, to carry their weapons concealed, wear polo style shirts or similar plainclothes, not to carry their badges. How do you identify yourself as law enforcement without your badge?
We can be thankful that level heads prevailed, somewhat. FBI members balked at the raid from the time they were first informed of the plan. It took several months for Garland’s demands, undoubtedly initiated by the White House, to be carried out. Time, during which no efforts were being made to retrieve any documents. Time, that may have been the difference in whether the Trumps were present at the time of the raid.
God works in mysterious ways.
