Western mainstream media is a wholly owned subsidiary of the plutocratic ruling class, which also owns the agencies with the authority to hold them accountable, so no.

At this point, the only way that any of them are going to be held accountable for anything is if the people rise up en masse and take back the reins of power. If that doesn’t happen, then the wealthy and politically empowered psychopaths who own and profit from the system will simply continue to destroy lives in order to fund their grotesque and wholly undeserved privilege.
