That's not what crossfire is. Crossfire can really, only occur with controlled weapons (a gun). Suicide vests are an exception of course. But see it's not crossfire if you say hands up or die to someone in a panic room and then shoot an RPG in there. This is because an RPG basically guarantees the death of everyone in that room. While with a MK1, if you're shooting at a cop and a civ in that panic room, if the cop is behind the civ and you already engaged him, that is crossfire.
