Why? A search warrant was issued based on probable cause.
The probable cause listed will likely be found to be insufficient if this goes to trial(it will never go to trial). Just because a warrant is issued doesn't necessarily mean the warrant is valid. Invalid warrants get issued all the time.
In any event, the warrant was not validly executed either. Every search they did was illegal as the warrant was not executed in the right county and it was also executed after expiration of the warrant. Every search they did was a separate assault and battery(both civil and criminal).
