The law MIGHT change? WTF?
What do you mean with "WTF"? What are The Facts?
The law may or may not change, but according to the law when the search warrant was issued, it was not necessary to request a separate warrant for electronics found within the approved search warrant location. Somewhere along the way, after the warrant was issued to search the car, the law changed and the harddrive took on a life of it's own - needed it's own warrant. That's clearly an appeal argument.
The warrant parameters should, by default, be grandfathered in just like the "double time for time served" was grandfathered in.
