Watch out! Stalkers and spies on the loose. Be careful though, these cops don't always know what they are talking about. Tips: If caught, claim that the cop is absolutely insane and that you were just watching and did nothing wrong. Another alternative would be to just flat out call the cop claim a fool or insist they have a motive, and if asked to claim, simply tell them that private information is private. If you put up a good enough argument, you may not have to sit in jail overnight for no good reason (good luck though, odds are you'll have to spend a night there.. these jailers are out to get you!). Town must be careful because the information given, specifically police reports, are not always credible.
Right now it looks like it's almost fool-sided... though the only 2 legit fool wins (not joints) were #1 - due to watcher apparently trying to fake a report and just happened to lynch fool, and #2 - watcher seeing a mafia and fool visit, misread, and say only fool visited meaning he had to be mafia.
