Do security guards need Armor and Higher Calibre Armor Piercing Firearms?

During that recent tragic Buffalo shooting, apparently the guard was able to draw on and hit the shooter, but the shooter had armor and the guard only had a low powered pistol. His hits failed to wound, and the brave man was killed.

Would you be comfortable with better equipped security professionals? I would like to know they're armed for the task in the hopes that such a tragedy could be averted.

My condolences to the people who were hurt and lost, including the hero guard who did his best.

Sad events.
