One thing I like about modern phones is that you can get to the emergency number from the lock screen or by hitting the power button a bunch quickly (depending on phone and settings), so it’s easy for an individual to get a 911 call going and on speakerphone without delaying anything else.
Point at someone, name them by clothing, and tell them forcibly to call 911
Too many times people think someone else is calling 911
