Oh, I think the whole "conviction" thing was the problem in the first place. Anyway, I don't even think that Snoop was speaking out of loyalty. Given his age, I doubt Snoop had an opportunity to meet Tookie before the latter went to jail; unless, of course, they met in jail, which is altogether likely -- you know, sitting around the recreation room, writing children's books, imagining how to make the world a better place through peace and tolerance. It makes you yearn for Malcom X.
Snoop's comments are as opportunistic as all the other jackals who made that man's funeral into such a circus. If Tookie was truly redeemed, if he had truly repented, you would not know it by the behavior of those in attendance. For Snoop to claim he was observant of Tookie's metanoia is the same as Judas noting that Jesus had a few good points.
