As a real life body guard...

Creasy is NOT a body guard. In either movie. In the 87 original, he was an ex-CIA operative, and a Vietnam Vet. He was living with his internal demons from that conflict. As a family member of a PTSD-sufferer, I know those demons, second hand. He had no training as a body-guard, other than being qualified to shoot well and being scary when needed.

If he had body-guard training, or if his past work was along those lines, such as a SS protection detailee, then I would have trouble with the points of detraction.

A CIA-operative/agent is trained to be inconspicuous, innocuous, un-noticed, and lethal when needed.

A Vietnam-War era soldier was a draftee, simply trained enough to not shoot their officers and then pointed at the enemy.

Neither of those trades make 'good' body-guards, at least not without a high amount of retraining of reflexes. Both are taught to not get shot, or shot at.

A PBG is a walking kevlar body shield. It is their JOB to take the (knife/bullet/bomb-fragments) while their protectee lives.
