What Tucker said would be irresponsible would be to put up videos of people instigating the event insinuating that they were feds. If he makes a mistake on any you know he will be raked over the coals and accused of being a liar.
So instead I think what they should do is get good still shots of these guys and show them to whistleblowers within the Federal government.
Or
Don't insinuate anything. Simply show the videotape evidence of people who instigated the attack on network TV for millions to see and ask if anyone knows who these provocateurs are. It seems to me that you discuss the best way to go about this with your legal department. It also seems to me that there have to be many sympathetic people who do have access to facial recognition software who may have heard last nights episode and may contact Tucker.
Also, it is very likely that Tucker already knows the names and already knows they work for the feds, but by doing what he did yesterday he makes it appear that someone watching assisted him with the facial recognition, in this way they help protect their source.
Their are multiple sources of Facial recognition. Google images can search for faces, Facebook searches, someone at the DMV, maybe a US marshal, a policeman for a large department like NYC could have access, someone in the FBI, someone who handles passports, etc. I would think after last nights episode there must be over a thousand people who could help Tucker figure out who these people are. Also what about a congressional committee? Can't MTG, or Matt Gaetz, or the Secret Service detail working with Trump, can't they do it?
