I’m noticing this tactic a lot of people shitting on activism by handwringing about “Oh I’m totally one of you and I totally agree with your goals but your tactics are just going too far!”
MLK decried this exact thing in his Letter from a Birmingham Jail:
“…that the Negro’s great stumbling block in his stride toward freedom is not the White Citizen’s Councilor or the Ku Klux Klanner, but the white moderate, who is more devoted to ‘order’ than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly says: ‘I agree with you in the goal you seek, but I cannot agree with your methods of direct action’; who paternalistically believes he can set the timetable for another man’s freedom; who lives by a mythical concept of time and who constantly advises the Negro to wait for a ‘more convenient season.’ ”
Like with the Witness K/Collaery cases where some of the trials happened in secret, and the appeals court found that the national security concern was basically bullshit, at least in Collaery’s case:

I’m glad something good came of that but it shows how easily the national security angle can be abused. We just started normalising government secrecy after WWII and it’s only gotten worse since. Nobody would’ve accepted “national security” as an excuse for this sort of flagrant abuse prior to that.
