There was something similar a while back marketed for private security contractors (by idiots referred to as "mercenaries"), a backpack that could be turned into a tactical vest. I'm guessing it's something similar, that this backpack will actually transform into a bullet-proof vest, though as some have said, it would be required to hold heavy ceramic plates to be effective against any serious weapons.
In fact, it could be counterproductive if the vest does not have the ceramics, in that the bullet would penetrate, and the vest would instead keep it
from exiting the body after it has lost kinetic energy bouncing around in there for a while.
I foresee a lot of parents buying this thoughtlessly, but I hope everybody does think twice before equipping their children with it. The result can,
as said, be disastrous.
I do, however, not find this particularly sick. It's a safety product, nothing else. It was sold before, and will continue to be sold after this
crisis. Everybody is bashing gun retailers and manufacturers for making tools designed to take lives. Let's not also bash companies that make stuff
designed to save lives.
