"[W]e see a heat-map version of it steadily light up in the areas where the women are being grabbed: mostly the lower back, backside, and arms."
This isn't exactly what the word "groped" conjures up in my mind. (I don't frequent the club scene, though, and I don't know anything about Brazilian culture.)
Nice demonstration. I'd like to see something similar done with men (not trying to undercut the point, just seriously wondering).
