Also, the “bulletproof” glass is usually polycarbonate (“Lexan”) layered with more flexible plastic. One of the problems is that exposure to ultraviolet light will over time lead to a degradation of the polycarbonate. If it’s in direct sunlight, it will often yellow and become harder to see through, prompting the users to replace it more often. Out of direct sunlight, the degradation is slower, and it’s usually not replaced often enough to maintain it’s rating for projectile resistance.
That being said, most “bulletproof” windows aren’t rated to stop rifle rounds, only handguns. And if they were shooting steel-cored AK rounds, it’s even less likely to stop ’em.

You don’t think the supplier LIED about it being “bullet proof” do you? It doesn’t look like they used a Fifty.

Blackwing, I’m sure Stop-n-Rob clerks and bank tellers everywhere are very thoughtfully looking at those dividers this morning…
