i think there exists a link though. these are RICO cases over the same type of thing (music piracy or whatever) in the same city at approximately the same time. that means people who weren't caught in the last raid may be present at this raid due to the likeness of the people involved in this music scene.
So, if there are gun dealers in Austin who are implicated in strawman purchases, that would justify a SWAT raid on your shop because an employee who wasn't at the first shop might have ended up at yours? Or, because you are in the gun industry, you have the "likeness" of a person who would engage in strawman purchases?
RICO goes a long way (way too far), but doesn't cover warrant or use of force guidelines.
