Consenting to be interrogated on Shabbos would involve multiple acts of chilul shabbos by the interrogators, if not by the prisoners themselves; and speaking when you know you’re being recorded is not so poshut either, though in an emergency one could find a heter. But being an accomplice in the police’s chilul shabbos is certainly not right.

And your proposal that parents should pick up the phone any time it rings, in case it’s got something to do with their children, is simply bizarre! And not only is it bizarre in general, even during the week, with your proposal you destroy the whole Shabbos.

Furthermore, even supposing that for some reason they had answered, and heard that their children were in custody; what could they do about it on Shabbos? It’s not pikuach nefesh, so they’d just have to have a tzushterter shabbos until it was over! How could that justify the chilul shabbos of answering?

The truth is that you simply don’t care about Shabbos, you don’t consider it important, let alone a mitzvah that is equal to all the other mitzvos of the Torah. Or rather, you do consider it equal to all the other mitzvos, because you don’t consider them worth anything either.

Jewish history will record him as a true rasha.
