Where to start? I suppose I am arguing semantics but words are important and JoeBas' statement is actually opinion and exaggeration.
Mostly I am challenging the assertion that it is common knowledge that the red team numbers have been abysmal. The actual results of DHS OI testing (the true "red teams") (not including the IG's testing), are held extremely closely, barely even shared with DHS' congressional oversight committees. So it cannot be common knowledge.
I do agree that it is common opinion the rates are abysmal.
