I agree that sometimes people do post online about committing crimes, but I do not believe USPS is better equipped than the FBI or DHS at handling it. The job of the USPS is to deliver mail. The job of the FBI is to stop crimes that will happen or find those responsible for crimes which have already been committed.

The FBI has more resources for investigating, finding, and assessing crimes. They also have additional intelligence that the USPS is not privy to. Why have an agency which has less resources and intelligence handle it? If it is a real threat the FBI can relay that information the USPS (and other agencies who operate in the area) to re-route their drivers or lock down their offices.

The USPS does not do anything so unique that it needs to a specialized investigative unit.
