After discussion in the staff team, we re-examined the case and agreed that in such situation securities did not break the rules and should not have gotten punished.
Civilians who got killed were already without the spawn protection, meaning that were able to shoot and harm the President which authorized the security team to eliminate such targets.
President entering the spawn zone made it disabled by the system. Civilians had 15 seconds of the spawn protection before it got disabled as well, giving them a chance of leaving the spawn zone.
Spawn killing warnings of Alexander and ABDULLAH_KING were removed.
