BASELESS conspiracy theory.
And its literally not "baseless" if you ask if its coincidental that he was arrested the day before he was supposed to testify, why not let the hearing come and go and if he was a no show then arrest him?
They are just questions.
Regardless, SBF was charged for conspiracy, fraud, collusion, etc. Why are any questions that would throw suspicion on other parties to the conspiracy immediately shut down?
"In the United States, Congress can also grant criminal immunity (at the Federal level) to witnesses in exchange for testifying.[1]"
