RMC, excellent post!!! I can only say that, unfortunately, many capt and sccm dont back you up 100%
and that is very frustrating...
I do understand there is pressure from the company not to delay flights due to bags being removed for the pax we are offloading, and sometimes they imply we (c/c) are the ones overeacting or being dramatic but I believe we should never be sort of "bullied" into carrying those pax who start being abusive before departure.
