It’s more than I’m used to seeing, for sure. Though “thoughts and prayers” is boilerplate/cliche at this point.
Some groups think they don’t think they need to issue statements because there is no internal impulse (what they do aligns with their values) and zero external compulsion.
If the Sikhs has "leaned out" and risked saying more (e.g., "...this tragic MURDER...") they might have risked contaminating the potential pool of jurors.
The murderer's attorneys* would have rubbed their hands in glee if the Sikh community had been harsher in its statement.
(Yes, I realize: Barristers!)
