Why is 9-11 not mentioned on osamabin laden's wanted poster?

Because bin laden was the financier. He was not personally responsible. The FBi SAys that there is no need to add it to his most wanted list because he is already # 1 on it. And his wanted poster says " he is also wanted as a suspect in other terrorist attacks from around the world." You can contact the FBi And Contact them about it.
