You mean like the "fact" posited by your side that Officer Sicknick was killed by the Capitol "insurrectionists"?

It's not just that this story fell apart, but that it took so long for it do so. All available evidence within just hours after this pointed to him not being beaten to death, including his family issuing statements to this fact that night, yet the media continued to run with it so much so that the Dems used it in the impeachment trial. It then became so embedded in the Democratic narrative, that nearly two months latter, on March 2nd, FBI Director Wray refused to give any concrete answers on the actual cause of death to congress including refusing to deny if it was from blunt force trauma.
There is not a single mainstream news source I actually trust anymore.
You have this plus the 60 minutes fiasco a couple weeks ago, the election story that Russia had a bounty for USA solders just recently fell apart, the GA election conversation that was used to tarnish Trump had completely made-up quotes, the dead solders are losers comments were bogus, all the panic porn around C-19 (which Bill Maher talks about frequently) including the constant faux praise of Cuomo for months on end ... and the list goes on and on and on.
We are watching the return of Yellow Journalism brought to us by the NYTs, WaPo, CNN, CBS, ABC, NBC, the AP, PBS ... pretty much all of the legacy news media. Even Emmy's and Pulitzers have no weight to them anymore.
Honestly, Glenn Greenwald is the only journalist I can name that I would trust. Everyone else, after the last four years, is suspect as far as I am concerned.
