it wouldn’t be hard if they were all drunk and passed out in different rooms in the house..
difficulty would be if the male was sharing a bed with one of the females ( which I assume to be the case)..even then being drunk would severely limit the ability of the female to react, assuming the male was taken out first..
it’s still amazing given the fact that no young adult that I know ever is outside of 12 inches from their phone, all that’s required is a voice command “ siri call 911” and the perp is screwed
