You must have another link. This one has nothing about Dao being diabetic. Also, the link you provided states in plain language that it “appears to contradict videos,” of the event. What source do you believe: security guards trying their best not to lose their jobs, or actual video of the events?
I read the report that claims Dao said he was diabetic. My take: it’s completely CYA absurdly implausible.
It is a fact that Dao was bleeding and concussed. In the scene as painted by the reoort, there were three security guards, multiple EMS personnel, and others present.
The claim that an injured 69 yo man could elude every person in such a crowd and reenter the plane is a self-serving farce. Are these people openly claiming to be Keystone Kops? If so, sad. If not, the story reads like a pack of desperate and silly lies.
Bottom line: the parts of the security guards’ reports that cover the video recorded incidents are demonstrably false. But your take is, as soon as the guards were no longer being recorded, they suddenly turned honest and accurate in their narrative.
Not buying it.
