one thing we can all say
as detailed as Pac life has been laid out by folks that knew him, loved him, hated him and wished they knew him
we never heard anything ever about Pac doing dumb shyt like "setting somebody up".
Well....At the 96 Soul Train Awards, Pac and Deathrow were planning on rushing the stage during Bad Boys performance. Only reason it didn't happen was because Don Cornelius wouldnt let Suges massive enterage in the building....though i understand this may not fit your meaning of "setup".
