A federal judge found him guilty of six or seven counts of profane language, indecent exposure (as the nickname implies... he QUITE HEAVY!!!); he once tipped over a LARGE round picnic table (the food went flying!) just by sitting down! but that's another story... he also got gigged for xmissions across international bourders (the F.C.C. claimed that Richard's xmissions could be detected in MEXICO!... He used 5-30 watts). A few other convictions too...
