The USA is much better at staging false events because it’s been doing so for much longer than most of other countries; since at least 1898 and the “Remember the Maine” false flag that was used to justify the Spanish-American War.
As far as the “confession” concerning what has been reported as Charlie Kirk’s murder goes, remember that Tyler Robinson isn’t even the first person to confess to shooting the Turning Point USA founder. Whatever the truth eventually turns out to be, remember, the one and only thing we know cannot be true right now is the Official Story as reported by the mainstream media.
