Stealth already reviewed their take on the rules for this, but I'm not so classy to cite a specific rule in this case with how aggressive you're being. So here, Rule 0 - if you're going to get SMGs unprompted as a non-antagonist cargo worker then you'll be dealt with. Stealth took responsibility for that ruling affecting the outcome of the round and as far as I can tell, between his spelling it out and your refusal to accept it, means it's pretty much going to stick. You were given multiple chances to provide a barebones reason for why you were opening a secured crate of automatic weaponry and beyond stating, "it was red alert", you've yet to provide one. As such, I am not entertaining the opportunity further.
With how flippant you have been between the quoted ahelp and throughout this thread, you will receive neither.
