The TSA is celebrating their part in helping Al Qaeda. It's not victimology on their part. It's maintaining their employment by continuing the absolute lie that anything the TSA does now would have prevented 9/11 then.
I assume the bracelets are yellow to reflect the loss of courage America has displayed ever since 9-11.
I'm not a huge fan of the commemorative wrist bands or other kumbaya pins that TSA comes out with to boost morale or teamwork. But that's just me. I'm good with just a moment of silence to honor those who lost their lives and then get back to work.
