Cha Ji-chul was the Chief of the Presidential Security Service, so why didn't he even have a pistol?

Isn't the job of a bodyguard to carry a pistol in their pocket to protect the VIP in an emergency?
I'm shocked—did he think that position was one where a gun wasn't necessary at all? ㄷㄷ
Still, he was a former soldier; if he had a gun, he could have drawn it immediately and won the fight.
