Will not happen, the consequences on future journalism would be catastrophic
Nobody 6 months ago would have expected the House of Parliament to conduct a 4 1/2 hour debate about what happened 22 years ago.
In any case, why would protecting the identities of blatant liars and propagandists be a threat to good journalism? What MacKenzie and the S*n were responsible for in the week after the disaster was *not* journalism. They printed disgraceful lies without ever checking the facts, then sat back and laughed as the families of victims and survivors tried to pick up the pieces for two decades.
Requesting the truth be told is not a threat to journalism. Publishing bullshit in order to smear fans and cover up culpability for 22 years definitely is.
