I believe they are already suing to recover property confiscated in a previous incident.
I think that there has been sufficient time for the Government to have filed charges regarding the prior incident. Having not done so, one would expect that Gibson’s lawyers would certainly ask that the case be dismissed, that the property be returned, and a return of the property in the latest raid, and that a restraining order against the DOJ be granted to Gibson preventing the DOJ from any further seizures unless the DOJ can clearly demonstrate that a prosecutable law has been violated.
