Travis_Bickle he's a total fake, even took the name of a proper criminal as his nom de guerre/nom de plume.
Ice-Cube & Dr. Dre have also embellished their bio's. Easy E was the only one in NWA who was involved on any level in what they rapped about.
Dre was wearing make up & sparkly gear a couple of years before NWA.

In Tupac's defence, when he joined deathrow, he certainly gave the ball a good kick on the gangsta front. Making up for lost time, though they reckon that it was his reaction to getting bummed in prison.
