Absolutely. If you do happen to roll that one monster on the random table that can avoid the alarm. I think if dealing with "jaded" players you build trust for a bit. If nothing happens, or the alarm just works enough times, you shouldn't be suspicious if it goes the other way on a rare occasion. I think unfair DMs, those who just make the bad thing happen to suit their agenda, are why so many are jaded.
Absolutely. Its a thing that always complicates trying to judge if this is going on, though: have you hit a GM who is cooking the books (entirely possibly for what they think is good purposes after all, though whether all their players feel the same is another question), a bad set of coincidences, or an overly sensitive radar on your part from past bad experiences? There's no certainty.
What is funny is that just as many GMs are secret player helpers as there are secret monster helpers. So rolling in the open gets rid of both to a degree. Some things can't be rolled in the open but when you can its best I agree.
I'm not actually sold cooking the dice to favor people is immensely better than doing it against them in some cases. As a player, if I'm going to have issues with how the dice go, I'd rather either use a system that doesn't have that happen as often, or one that has mechanical processes (metacurrancy, say) to mitigate.
And yeah, some information access rolls seem to lose something if rolled in the open (some people don't care or have good enough firewalling that it doesn't apply, but I don't think those are typical). But for things like combat rolls and the like, I've concluded its all to the good.
