Don't use smart phones or apps if you ever really do decide to riot. Phones can and will give away your GPS data to law enforcement and they'll know if/when you're at a riot. Some spooky shit happened in Crimea. Anti-Russian protestors were ``disappeared'' thanks to the GPS data indicating that they were at the scene of the unallowed riot. I can't be bothered to list a source but I'm sure you can find this on a search engine if you really search hard enough.
