TrustExecutor I know about the BFU state, the issue is our police (Russia) politely asks you to unlock your phone. And oficially you are not obliged to help them with this, but if you dont - they will try to cause all kinds of bureaucratic problems for you, or they will just push you psychologically, and after keeping you in custody for couple of hours they will probably free you even if they dont check your phone, but not everyone has couple of hours to get through all this, especially when plane is about to take off soon. So when police politely asks me to unlock my phone, and I have nothing to hide - you can call me a sheepie (and it is true), but I will prefer to not make it complicate for myself.
