Let’s all be kind.
As I have said if the government doesn’t want wild stories, rumors and conspiracy theories to grow then TELL THE WHOLE TRUTH.
Coverups to cover the rear ends of the diversity hire boss, or of the agents in disarray only spawn silly season stories.
It only hurts the people involved as every hour, then every day going by with “we will not reply to that, you can ask the other agency when their full investigation is complete.” is the strategy. Only slightly paraphrased from the first 24 hours of news conferences with reporters.
But they do want wild stories to grow and spread. The more and crazier the stories, the better for them. It provides smoke to help cover up what really happened. And when the crazy stories are debunked, it smears the people who are following the correct trail. Some of them will get discouraged and fall out of the hunt. Other voices will get drowned out by a manufactured consensus about a "lone wolf killer", and "we can never know what happened".
Or whatever the party narrative turns out to be.
