Time? He died at the cops feet....they used every second of time available.
Position? He took the high ground and went for the officer where he ended up dying.
Backup? Unless his partner can turn back to hands of time there was not anything else backup could have done....he hid the nakednin his pocket until the cops arrived.
Armed to the teeth? A handgun is only marginally better than a knife.
Authority? The crazy suicidal guy did not respect their authority....authority is not power.
LOL, thanks for playing.
