Court curtails border agents' cellphone searches

A federal appeals court has ruled that border agents cannot do automated forensic searches of cellphones without reason to suspect their owners committed a crime — and they actually might need a warrant even then.

Why it matters: Border agents have extremely broad authority to detain and search people coming into the country — so much so that agents have more or less taken free rein to search devices of anybody they choose.
