It's too late! No one can stop it now!
But don’t worry; I’m not gonna pull that very often at all. I was okay with breaking it in this one instance because the cop is really just "Nameless Dispensable Individual #1", so as the St. John's would say, "He was gonna die anyway."
I agree, the cop was a pretty cool guy. They gave him a decent personality right before they killed him off. He probably would've been a cool companion to have for a while, but alas, he served as the last person you ever talk to in the "normal world", and nothing more.
Rest in Peace, Nameless Cop.
