Any terrorist atack in past 20 years coz by gaijins?

And no gaijins who live in Japan are on this forum?

Last thing i wanna know if Japanese police will check my passport if im not doin anythin suspicius ( lests say walkin on street) And no police in my country dont check ppl id if your not breakin the law, ive never heard a police man check you beacuse your gaijin black etc etc. And no, there are no terrorist atacks in my country(BTW i never head about any terrorist atacks in Japan) Its not polite ive been in French, UK , Germany and cant say a bad word on police there i could even get a help from them. If a police in Japan disturb gajin even at late night its racizm guys.
