uneeq,
There’s a teshuva from R’ Moshe as well (I posted earlier) and in the sefer ????? ?????, he uses the R’ma (alomg with other heterim) to allow asking the police to detain a recalcitrant husband who might otherwise leave his wife an agunah.
It’s not completely nidcheh in halacha, you just need to know where to apply it.
It doesn’t apply here, though – all of the seforim who talk about such a case asser.
