Please keep in mind that Al Capone, notorious gangster, was convicted of tax fraud because that was what they were most able to readily prove and put him away for. Sometimes cases hinge on what the rules readily facilitate rather than on details that one might find more morally satisfying. Those cases may be brought for the right reasons but the law sometimes is at odds with going after someone "for the right reasons." You could consider it a kind of legal hack. It happens fairly often both in crime or legal drama shows and in the real world.
