You need to have proof that the software is being used. You also have to provide notice and cannot expect to just walk up and demand inspections. Also, this is a private company so they have no authority to do this.

The primary bit of evidence to the BSA was/is from disgruntled employees "ratting" on their employer. Is that sufficient evidence of a crime to justify a warrant for any TLA to do an investigation? If not, that's the only way you're looking at my computers.

Again, laughing in their face would be my response.
