Uhm, yes...
Zimmerman _needs_ their support. Zimmerman’s own life is n danger, and their speaking out on his behalf might actually make a difference to his survival or how his life will be from now on.
They owe him their lives and should do what they can to help him. It’s about honour and decency, things that would have been a matter of course not long ago...
Disagree.
They have no moral obligations to him other than those they would have if he were not a public figure.
