I'm guessing SM is not wearing his jumpsuit and shackles as to not prejudice the jury against him. I imagine if he were incarcerated for a violent crime (rather than obstruction), it might be a different story. I could be wrong, but I doubt it, because I watch a lot of Law & Order: SVU.
That said, if TM were to testify (and I don't think she will*), would it be a different story for her as a witness? She's incarcerated for a much more serious crime, and she's not the one on trial. Does anybody know if she'd be in her jumpsuit and shackles, like DD was today?
*I don't think TM will testify for the State because NL said the one other potential witness they may present will be very brief. When it comes to testifying, TM can't spell "brief." I don't think she'll testify for the Defense, because that would open her up to NL on cross, and she's currently incarcerated for conspiracy to kidnap, as in SM's co-conspirator. The jury wouldn't need a calculator to add 2+2 together.
