So, it seems like half the time when I visit this SE site, when I look at questions here, I wind up leaving a comment to the effect of "What location are you in? Different places have different laws" on questions that haven't specified their location. Different countries have different laws, different states have different laws, heck - even different cities can have different laws! Without knowing the jurisdiction of the question, it seems scarcely possible to give an accurate answer to nearly any question about the law.
Should we make it a rule that all questions must include a location tag, similar to how the RPG StackExchange site makes it a rule that all questions must include a tag that indicates what game system the question is about?
