In court? Not really. These warrants are on solid ground from a legal standpoint. To the point that fighting them could be a sanction-able kind of grandstanding.

Sanction-able? I'm not saying you shouldn't comply with a valid warrant, I'm saying that you should object to whether there was probable cause for the warrant.

Yeah you shouldn't object in bad faith. I.e., you need to genuinely believe there's no probably cause here, and that's not a reasonable position.

If they don't have any evidence that'd lead them to believe the data they're searching for is on that laptop, then you can reasonably object that there's no probable cause to search the laptop.

This is my thought also. So they're only holding the keys to prevent anyone from whining about lost data, they don't actually want to be responsible.
