I don't know where you're getting your information, but it sounds pretty nonsensical.

Quoted from my comment above:

I know; I was in the US military during that time and served in Iraq briefly in 2007.

Personal experience working for the US government. It was a common news thread at the time, and our government was afraid of people learning more about Osama's specific intentions. Sure, there was a lot more to it, but the main story our government wanted squashed was the idea of revolution. They worked hard to redirect our attention toward revenge on the attackers instead of questioning why they attacked us in the first place. They didn't want the public poking into what our government was doing that justified an attack on our nation, and they definitely didn't want anyone showing sympathy to any degree for Osama.

Again, Americans were politically blind back them. We had no idea what foreign affairs our government was up to at the time, or what atrocities we might be committing in the Middle East. This brought a warfront to our front door and got the average citizen involved in worldly affairs overnight. Our government found themselves suddenly needing to control the narrative and refocus our anger at the scenario that played out in our own backyard, as well as those involved. We put a target on Osama's back once he claimed responsibility for 9/11, and that became the headline for every news story going forward.
