Could location data be altered or spoofed?¶

Yes. Developer tools, specialised apps, modified devices and account use from another location can create false or misleading points.

Look for a demonstrated mechanism¶

Relevant indicators include mock-location settings, privileged software, unusual permissions, impossible travel and conflicts with sensors or provider records. Installation after the event does not prove earlier use. Stale data and ordinary error can also create anomalies.

Compare independent systems¶

Test GPS against Wi-Fi, cell sites, network addresses, photographs, vehicles, Bluetooth and transactions. Identify which device and session supplied the point and when. Spoofing should be an evidenced explanation, not speculation attached to every inconsistency.
