To be clear, then, either:
-- they were extremely skilled, wily, and accomplished outlaw gangs way above average in intelligence, seeing as how although all 177 except for one were Texas residents, the vast majority -- two thirds of them, in fact -- not only had zero convictions for crimes in the state of Texas, but had totally clean records. That's quite an accomplishment for a criminal outlaw gang member, let alone 117 of them. I mean, I gotta be honest with you, Hulka -- I know a few rough bikers, and I can't think of a single solitary one who doesn't have some kind of record, and I know for certain sure that the really bad dudes had records from the time they were 23 years old or younger. So you are certainly right, then, when you say these very, very clever and skilled bikers were "not your average group of guys." They are way, way above average and extremely accomplished.
OR ...
-- Texas police are inept boobs if they manage to let 117 of 177 violent outlaw gang members slip through their fingers again and again and again.
OR ...
Hulka is full of crap. :^)
