That would have to be *quite* crime-ridden.
We sometimes had someone ask for .236" polycarb for a "glass" door, 
usually after the store had been broken into a few times.  Even versus a 
big, enthusiastic thug with a sledgehammer, the polycarb will win every 
time -- it'll get scratched but it won't break.

Bullet-resistant (not "-proof") "glass" is normally a sandwich of two to 
four layers of laminated polycarbonate and/or acrylic ("Plexiglas"). 
AFAIK it comes in .750" and 1.25" thick, rated to stop a .38 cal and a 
.44 magnum, respectively.  OTOH I've seen a 1.25" sheet with a slug from 
a 9mm "Hi Power" pistol, which penetrated three of the four layers, ie. 
through 1.125 inches.

The thicker version might stand up to 5.56 rounds for a while; I 
wouldn't bet that it would stop a 7.62, and I'd be surprised if it *did* 
keep out a .50 cal, although it would probably change the angle and make 
it hard to place your shot.
