If there was no actual spying, then there's no victim. If someone gets pickpocketed on the subway, saying "You should have protected yourself better" is victim blaming, sure. But if someone doesn't get pickpocketed and then points out how there was a foreigner sitting right next to them who could, theoretically, have pickpocketed them, should they have chosen, and while the foreigner didn't pickpocket them this time, you know how those foreigners are... then "Why didn't you just get up and sit somewhere else if he bothered you" is a particularly polite form of what you perhaps ought to tell them.
