I don't know which episode it is, but there's one where there's a bus or a train or something, and all the passengers are dead. Walter kneels down infront of a seated woman, and proceeds to peer directly up her skirt!
One of the policemen accuses him of being a pervert, but he says, no, not at all, I'm simply just checking to see if she has soiled herself - Im a scientist!
Apparently this placates the police who allow him to continue... ???
I wonder if I could get away with the same thing when I fantasize that a woman on the bus has soiled herself? Probably not...

Typical 'One rule for them, one rule for us' mentality...
At that point I realized how unrealistic and out of touch with reality the show was, bemoaned the fact that I will never get to check up a random womans skirt for soilage (infront of the police) and immediately stopped watching...
EDIT: As I fancied a fap, I had to research the scene, to check it wasn't just a fever dream - While I couldn't find a clip, here's what I did find
