You forget that humans cannot see Wesen when they are woged unless they want to be seen. There is no reason to think that either the Drang-zorn or fly guy were visible to humans. While it is true that Trinket did woge to that point in order to scare Nick and Hank, he jumped to his death afterward. He would have been falling too fast for anyone to see what he was and once he went splat he would have reverted immediately. Volcanalis only showed himself in areas where there were no witnesses (that women's house may have been in suburbia, but Volcanalis escaped Nick by melting through a grate and entered the warehouse via a manhole cover, so he can move underground with ease). That leave Tuesday's bird guy. I don't think they saw him transform back to a human. When he shifted back, there is a noticeable lack of surprise sounds (gasps, minor swearing, etc). They saw him, backed off to the point where he was not immediately visible, and then he changed. After they look at him again, they are probably going to assume that this guy had some kind of condition that caused him to grow feathers. It is a tenuous theory, but you have to remember that most people will go for the most ratio national answer first, and from the perspective of the SWAT team my condition theory is far more rational than the idea that there is a race of shape shifting monsters.
