Doubt it. I can hardly verify things happening in my city even if I try, let alone e.g. things happening on the other side of the globe which the media keeps telling me about in order to drum up the next cold/hot war. I used to be able to tell Photoshop jobs by non-experts, but soon enough everyone and their mum will probably be able to produce completely fake videos indistinguishable from real ones, so even "video evidence" will mean little.
