Millions of Federal Employees are directed to work from home by OPM or their Agency. Search warrants aren't required to search government property. Can you imagine how quiet it is going to be in the hallways of all those thousands of federal office buildings? Imagine all the secrets being kept in safes and office drawers, behind the closed doors.
No, and I'll admit it may be just fanciful speculation on my part. I've seen a handful of "work from home" reports from other government workers and took the natural course of progression of this event. Non-essential employees are regularly directed to work from home during any number of contingencies.
