While on Interscope he was harassed frequently by police for protesting against them in his first two albums. Most of his cases sparked up after his first album release. Songs directly referencing police were often cut such as “Runnin” which was cut down from “Running From the Police” and the initial released version had all Police references blurred out. He also had to cut other songs of his Thug Life and MATW albums that were attacks against the police and gov’t. In addition, Interscope started pulling him off of projects such as the song he did with Madonna.

"It seemed a little unimportant, when he told me I smiled" (2Pac – Blasphemy) | pending

He’s saying he didn’t know how to translate his “father’s” advice at such a young age. He doesn’t know the trials and tribulations of men.
