There have to be, but it might be hard to get data, and/or controversial/inflammatory to talk about it. I don’t know if Google will release any statistics on all the cases they know about, and I won’t hold my breath, but that would be pretty enlightening. Things that are likely well above 20% include men being the perp in much larger numbers than the company’s gender distribution (national stats are roughly 80/20 [1]), whether the perp is a higher rank and/or direct supervisor (national stats say this is ~40%, whether the victim was threatened, and what department the people were in.
