nOmesorah -“When the drunk is actually starting to drive [while impaired] and there may be people around (Or if there are people with him in the vehicle.) he is a rodef. Not before that.
Breaking into a house is not [yet] a rodef. He is given a lifeless disposition because of two factors. 1) He is in the process of theft. 2) He may become a rodef”
Obviously your Not familiar with the Torah. My last example was Haboh B’Machteres. He’s a Rodef as soon as he breaks in.
The same is over here. He was about to drive the Car – as s/o intoxicated.
The cop pulled him out. So what are you proposing the cop do next? Let him go or arrest him?
My impression from you is – he should let him go.
But that would be against the Torah, because he’d just go back to Driving.
So he had to arrest him – to stop him from being a Rodef!
