Greyhound has finally, definitively decided to stop serving up its customers to US border agencies.

A week ago, a CBP memo obtained by the Associated Press made something clear to CBP agents that should have been clear all along: they could not perform sweeps of buses without the permission of the bus driver or the bus company itself. Unfortunately, this means a bus driver can consent to a search on behalf of passengers, but it still was better than Greyhound's stance. The company had stated that it believed it could not legally refuse to allow CBP officers to board buses.
