Yes, she’s technically trespassing, although she may have had “permission” from the owner prior.
As for your assumption we’d all assume the man was a peeping tom - ridiculous and reactionary (i.e., men are always put upon and it’s all the fault of feminazis). Same thing - he can’t help but see some stuff from exposed windows. If he openly COMPLAINED about it, as this woman did - how could he be called a “peeping tom”? Hole in the logic, there.
Or maybe from the present owner or residents.
