The last check on power is murdering politicians in their homes? I beg to differ. If the situation is so bad that violence is truly necessary, the last check is an organized revolution, not an assassination. If the figure is a genuine dictator and important enough to have real power, they would have extensive security surrounding their home anyways. This fantasy of assassinating a would-be Putin or whatever does not justify exposing the addresses of city councilmen or judges or whatever random public servant somebody wants to kill over their grievances.
