I generally expect very little from management, TSA or anywhere else -unless it's directly tied to their personal compensation.

Behind every abusive TSO, there are layers of AWOL or complicit management backing his/her every action.
If an LTSO, STSO or manager says "I wasn't aware", they are either lying or they weren't doing their job properly. Either way, they're directly responsible.

Alongside every abusive TSO, there are many many other TSOs, backing and encouraging his/her actions. If they don't "see something, say something", then they are just as responsible. Don't pull the old "It wasn't me, I just stood by and snickered and said nothing" excuse.
