I like that you included a study that supports for point. I think the quote in the CNN article is not used correctly in their claim. Just because someone's breast implant was a likely stop to the bullet in no way means that all implants are bulletproof. I looked more into the study you found and it does say that a breast implant has the ability the reduce a bullet's ability to penetrate, but to say that all are bulletproof implies that all breast implants are 100% bulletproof, which is clearly not correct. I agree with your explanation and appreciate the source that you gave to disprove this claim.
