I'm not american so can somebody please explain me, how is deleting logs and every trace of your actions helping with government efficiency?

To more efficiently rout trouble-makers and unions.

The administration has said they want to start gulaging citizens. They aren't going to do it randomly, it'll start with sure actual criminals, and then people they think you'll believe are criminals, but why would they stop there. What can a palantir-ICE collaboration do with this data. "First they came for the trade unionists" is halfway through the poem you know.

Combined with "oops can't get them back" it's very powerful. Combine it with not advertising faces of snatched people on broadcast TV, and it's a very useful tool inded. People will just disappear. It won't be legal or illegal, just a thing that happens from time to time. Police won't search too hard for the missing people, because no good can come out of finding out.
