For starters, it didn't go missing and for the most part wasn't spent or even actually exist. Loan guarantees and overnight loans are a whole different ball game. If provide a $1B overnight loan for you 10 times, I haven't spent $10B dollars. Same if I had guaranteed $100B. Save for a default, I haven't spent anything (actually I made money). The reason why the Fed didn't announce which banks were in trouble is stunningly obvious, which is why outside of internet conspiracy circles this video isn't big news.
