Joseph,
Avram, in the frum neighborhoods of Brooklyn, Hatzalah often arrives in about a minute. This is very possible because there are Hatzalah members distributed within a block of most frum families.
Thank you. In that case, I’ll posit that “under a minute” was perhaps counted from the end of the call (i.e., the ambulance was dispatched while the dispatcher was still on the phone). In that case, it still does not make sense to ask why Ezras Noshim did not call Hatzola, because they would have seen that the man was on the phone with them already. I’m perceiving that this unfortunate event is being used as fodder in a “conflict” between Hatzola and Ezras Noshim?
