In the real real world, not all police has that or uses it in every raid. We got visited once as a group of people some ten years ago, coordinated to happen at the same time at different locations across multiple states, and at none of the locations they brought any such equipment or expert, even though both the accused crime revolved around computing and warrant specifically was for computer equipment. They asked nicely for passphrases and since we didn’t provide any they got nowhere. They even allowed us to power down some machines for them, haha.
