I can also find nothing about this on the BBC website despite various other sites claiming the video is BBC-verified. It's not mentioned in their BBC Verify thread. I wondered if they had had doubts since broadcasting it last night.Was that video ever confirmed as being a real deal and depicting Alex Pretti? I know there were claims BBC confirmed it's authenticity, but there is no such communicate on the BBC page. I would be careful with that vid, there is a lot of fakes in circulation.
The Guardian, however, appears to confirm it.
Videos show altercation between Alex Pretti and federal officers 11 days before he was killed
Three newly discovered videos show the Minneapolis ICU nurse being tackled by federal agents in a prior confrontation
If genuine it is background information, nothing more, IMO.
