JUDGE RIPS MATERIAL WITNESS JAILINGS "cannot be used to imprison potential grand jury witnesses"
Yes, because the "Material Witness" rule does not apply to grand jury investigations. Its spelled out in black in white. Its not even a "technicality".
I got into this discussion yesterday on another thread. I will say the same thing: If they wanted to detain these people as "terrorists" under sedition laws, and they had proof, then I would have no problem. But don't manipulate the law to one's liking to detain whoever for an indefinite period.
