But since there were two people in the room with Anna, couldn't one of them pick up the hotel phone and call 911?
Usually the phone is right by the bed, on the bedside table.
If Taz wanted to keep the "airway" open for Anna, couldn't the other person make the 911 call??
Yes, of course. Since there were 2 people there, one of them definitely COULD have called 911. Totally true.
