This video isn’t about “bulletproof backpacks” and “bulletproof hoodies” and all the other misery-profiteering school products out there—but it illustrates an important point, which is that this shit isn’t a +4 magic shield; you have to stop the projectile, and you have to do something with the force it’s exerted, and you have to be able to get up and get moving to avoid getting shot in the face or the crotch or anywhere else that’s exposed because you’re on the ground and gasping. Life isn’t a video game:
Heck, just jump to ~3:34, and see the wreckage caused by an extremely common, extremely legal gun—even when the bullet is stopped.
Incidentally, here’s the testing documentation for the bullet-resistant hoodies featured in that BoingBoing article linked above.
Do those hoodies stop a .44 Mag? Yup! Zero penetration. That is indeed impressive. But look closer at these results: the witness panel was deformed by 1.25 inches on average. That’s how far that bullet would go into your body—even though it hasn’t torn the fabric. It’s called “soft body armor” for a reason, folks. The manufacturer implies that the hood will protect you, but that’s a load of shit: If your skull suffers a blunt penetration of 1.25 inches, you are dead. Your brain is only about .5 inches from the outside world.
