I also think the way DOGE has gone about their business is the only way that'd work in a systemically corrupt environment. If you give these institutions ample warning they'll bury or destroy any and all evidence, because that's how it's been done for decades. That doesn't work.
Ample warning of what? Evidence of what? If the goal is to, say, shut down USAID, to do so legally you just need to get Congress to pass a law shutting down USAID. No "evidence" is required, and warning is irrelevant. What is a shut down agency going to do with "warning" that it has been shut down?
