Re: Just say no
Well, if you already end up in the yes or no part of the conversation, you're already at a certain level of risk. They might have plans if you say no to make sure you don't report their request to someone. While those plans might be along the lines of "put that guy and the people near them on the don't try list, get the requester out of the country, and send a new requester next time just in case", they might also run along the lines of "turn that guy in right now to get them caught or maybe use a nearby object to attempt to create amnesia so they don't remember what I look like [procedure may have side-effects]". If you agree long enough to get free and turn them in, not only might you have a better safety record but you might actually catch these people, like this time.
