I like the idea of reporting it stolen, the problem would be filling out the police report in a way that's factual, honest, and doesn't give away the "authority" of those who stole it.
The government must have paperwork for property they seize, and usually your supposed to get a copy of the items seized. Lauren, I'm guessing they skirted this procedure, and you may be able to leverage that against them. Anyone have experience with property seizure procedures?
