As far as i recall, ALL killing has to be done with a VALID RolePlay reason.
So for example, In a hostage situation, you have taken a hostage and orderd cops not to come closer, yet they do.
As you warned the cops, and its with a valid RP reason, you may slice his throat, don't exept cops to ignore thou.
As i think the meaning of this particual announcement is to make sure, that of you go up to someone randomly, and slice his throat; is, was, and always will be classed as DeathMatching.
Asfar as i'm aware, theres no 'new' rule stated on this subject, apart from the old "Don't DM people" rule.
If i'm mistaken, feel free to correct me.
