One Minute - S3-E7
Factual error: As demonstrated in the earlier scene where Leonel shot the truck driver/arms dealer, bulletproof vests do not make the wearer immune to bullets. Bulletproof vests are only designed to stop penetrating injury- they do not counteract the high energy of an impacting round, which can easily break ribs and cause internal injury. When Hank empties Leonel's dropped gun into Marco, Marco is barely staggered despite the fact that he just took five rapidly fired bullets in quick succession to his upper chest. That many hits at such close range in such a small zone would have, at minimum, shattered several of Marco's ribs and potentially punctured one or both of his lungs - both critical and incapacitating injuries on their own. As a result, Marco should have been unable to lift his gun to shoot Hank twice in the chest, much less swing an axe. Additionally, at least one bullet appears to strike Marco's clavicle and upper shoulder- both areas that are not protected by the vest. (00:44:00 - 00:45:00)
Suggested correction: Bullet proof vests disperse the energy of projectile impacts. Bad bruising can result but certainly not broken bones or punctured lungs.
They are not bulletproof vests. The correct name is bullet-resistant vest. Smaller rounds, like a .22 or .25 caliber, can penetrate a vest by going between the protecting fibers because of their smaller size. Also, they are not designed to resist high-powered rifle rounds.
