(a) The pirates deserve to be slammed for STEALING (Yes I said it, because that's what it is!)!
(b) The pirates ALSO deserve all the due process and constitutional protection that the US has to offer--and the RIAA assiduously tries to ignore! You can't slam the thieves until the thieves get a FULL and FAIR day in court.
The Pirates deserve to be hammered, but only after every last one of their constitutional rights is respected!
Assuming we're still talking about digital piracy here, it is NOT stealing, it is infringing. The two have separate legal meanings that have to do with a scarce good being taken away from another person/entity. Copying music does not take that original away, ergo it cannot be stealing, it is infringing.
