Once this guy knew who he was doing business with, it gave him two crappy options:
1) Turn informant for the government. His customers would know in a moment that he flipped once they see that he's moved out of his house and suddenly has the money to open a fancy storefront with all the bells and whistles (bugged to the gills). Once they figure that out, he and his family are as good as dead.
2) Take your chances in court. Since the federal government moved the venue to Kansas, that'll practically secure a conviction for an LA Latino who can easily be painted as a gangster living large while working on spec for the drug lords. Also, this sets an example for those who refuse uncle sams generous offer to turn informant.
