It is intended for all characters to be able to enter, traverse and hang out in towns no matter their notoriety state. To be clear, murderers are allowed to enter protected towns and hangout, but they are unable to use any vendors in town, and they are subject to being attacked by anyone as well as being Guard whacked if they commit any crimes. Furthermore, it's intended for all characters to be able to enter the West Britain Bank rooftop hangout, even murderers. Combat is prevented from this space, as well as using the ladders/teleporters to the roof after engaging in combat, so there should be no concern about this.
