There are two names of persons suspected of shooting Ms. Babbitt.
Both of them are black.
Both are lieutenants in the Capitol Police.
How many "black male lieutenants" can there be in the Capitol Police force?
I suggest that an article be published or broadcast (Tucker Carlson might be the guy who has the intestinal fortitude to do so) naming them BOTH as "possible shooters".
Then... sure as shootin'... ONE of them is going to step forward (perhaps through his lawyer) to claim "it wasn't me".
They may threaten a lawsuit, but I sense enough evidence is out there (evidence that could be taken to "point at" either one of them) to render such threats moot.
If the guy was white (or Asian), the name would be "out there" already.
(see "Lon Horiuchi" about that).
But because he's black, the guy is being protected.
