Lawful Interception Warrant and Intercept Product

Detects telecommunications interception warrants, stored communications warrants and the intercept product they produce (call transcripts, line / session logs, intercepted communications) under the Telecommunications (Interception and Access) Act 1979 (Cth). Disclosure of the existence of an interception warrant or of interception product is a criminal offence under the TIA Act and alerts targets to switch to unmonitored channels. Absorbs the former lawful-intercept-transcripts classifier.
