As I investigated with `/notarget`, it's technically possible to legitimately (without cheats) clear the most of the map with stealth approach except the path of the officer and the courtyard in front of the bank.

If the officer notices a dead body, he calls for alarm; if I tried to kill anyone at the courtyard in front of the bank, someone surely sees it calls for alarm. But if I just follow the officer with /notarget, he surely eventually gets into the bank.

Assuming that the officer won't bug and not stuck inside of his building or in front of the bank door (that tends to happen), is there a way to get in the bank with him? Or the mission is designed with the assumption that the player's cover will blow sooner or later?

Thanks!

Edit: PS; I don't use RealRTCW, I instead use iortcw with Mod DB release of the mod (Standard installation for iortcw).
