Ken,you can and do get 'bad' glass from time to time,normally these are picked up in pre-delivery inspections by the manufacturer or vendor.
As I'm sure you're already aware laminated glass is much less forgiving than tempered and 1/2" sounds a little more than I would like to persuade to fit,and even assuming you did get it fitted without cracking,you would then have a permanently stressed windshield.
One heavy road bump or rock chip and it's game over...
Personally I would contact LMC and ask their Technical support if there's been any other instances of bad glass,these things usually happen in batches.
