Um, no, I simply googled the guy, then posted things from sources other than PV, NONE of which can verify the video. Then it opened up the door of the video might be fake. Any good cynic or simply thinking person will question the veracity of seemingly fantastic single-source "evidence". So then I found a really well-balanced snopes article where they just tried to find the guy and even admitted he might be who they say he is. Then I got curious and did my own search on LinkedIn. Found hundreds of execs at Pfizer, but not that guy. To be that casts doubt on the veracity of the evidence. Then take into account that PV is known for putting out evidence that has been trumped up or outright faked. All this together raises a reasonable doubt.
So can you or can you not provide any evidence at all the guy exists and is who they say he is? Habeas corpus, as it were. A simple yes or no will suffice. Or do you want to deflect some more?
