Spawn is not resting area. So you gotta be aware of your surrounding.
Then why we got a command named /Duty and a warning called 'Follow /Duty' Security's duty is to protect president, not kill civilians!
Black Panther mentioned that this happened when the President was in the Civilian Spawn. Security's /duty is to protect the President.
So that means he is free to kill anyone who may be a threat to the president in the vicinity.
Bullets don't work under SP and only thing that could possibly kill president are grenades and chainsaw which I don't know why hasn't been disabled too. Disabling the Spawn Protection would only give civilians more of a chance to kill the president especially snipers who won't need to come out of Spawn and become vulnerable on a more open ground.
10 civilian deagles at one place would only increase the chances of president getting killed.
Why not disable melee weapon and /holiday eng spawning entirely under SP?
