Testing Communications Evidence

Readiness training. LEA.Training does not grant any official certificate, licence or authority.

Call records, cell-site data, IP records and chat exports look exact: rows of numbers and times. But each row was made by a machine for billing or for running a network, not for a court. This unit gives you standard questions for each kind of record.

Focus: ask what the record is, what one row means, what is missing, and how far the conclusion goes beyond the record.

Learning objectives

  • Apply four standard questions to any communications record.
  • Test a call record, a cell-site claim, an IP record and a chat export.
  • Tell a record from a summary, a chart or a map made from it.
  • Explain how courts in several systems treat the way location records are obtained.
