Well, they weren't ambushed (you still can't produce any source for that, remember). As for what I called them? Gangsters, yes. Mafioso, no. I've already explained that mafioso reference to you twice, but you were too slow to comprehend, so I won't bothering attempting again.
"Why is it so hard for you to admit that you said that, and have already determined guilt/criminality all on your own?"
Calling someone a gangster, when they wear their gang insignia for the world to see is not "determining guilt", no matter how many times you try to equate them. You can call a pig a cat a thousands times, but it ain't never going to purr.
Maybe an example will illustrate that point for you, since you don't seem so good with abstract concepts. If you saw these three fine gentlemen approaching you:
I think you would agree you could say they were gangsters, based on their wearing of gang insignia, no?
