I'm very familiar with tempered "safety glass".
My son bounced a BB off of a brick on our patio and the ricochet dinged the lower corner of a tempered glass sliding door. Over the course of 24 hours, that glass sat there and slowly crumbled into ~1/4" chunks. Fortunately, it was double-pane, and we were able to stay inside and watch the disintegration of the outer pane in safety.
The undisturbed sheet of glass stayed right in place as it crumbled -- and, it was only when I gave the whole door a good bump -- that the sheet collapsed into a pile of ~1/4" "cubes" on our patio...
That gold-coated "Hurricane" glass is definitely not the same...
It’s definitely not like typical safety glass. And it doesn’t break into very large pieces like plate glass would. More like two windshields with a flexible plastic layer between. Very difficult to break and it would have taken some time for the shooter to get it done. Even if he had some help.
