Bullet resistant is what is wanted and it looks like it passed.
Bullet resistant. I understand the concept, and believe the titanium passed. But it reminds me of the time many years ago, when a salesman tried to sell me a pair of boots. I was looking for guaranteed waterproof, leakproof hunting boots.
He told me they were not waterPROOF, but they were waterRESISTant. When I asked him what THAT meant, he said they WILL leak, but they don’t WANT to.
We say something similar in machine design:
You can’t make it idiot proof, only idiot resistant.
