There was of course a reason why the Secret Service raided them, but that doesn't mean it was a good reason. At the time, everybody was shocked and the courts sided with Steve Jackson, but with the past 15 years, I can imagine people are now more used to this kind of invasive, ill-justified raids by law enforcement organizations, and more willing to accept this as normal behaviour.
It was a good reason even if they were incorrect regarding their suspicions, and they did not have either the proper paperwork to enter the premises or the legal authority to remove what they did. As someone personally involved in the whole affair I can assure you that it was considered excessive and the Secret Service rightly deserved losing that case.
