Detective Shanahan told me in the October that if I had, we would have had a very long and expensive argument about authenticity, and that she has watched two cases come apart over exactly that, because the moment a civilian has edited a file the defence gets to ask what else was done to it.

What I did instead was pay thirty-nine dollars for the year’s archive export, which the manufacturer provides, and which comes with a hash and a log.

And in that log is the thing that won the biggest fight in the whole case.

Because the defence’s first motion, filed in the January, was not about the push.

It was a motion to suppress the audio.

Arizona law makes it an offence to intercept an oral communication without the consent of a party to it, and I was not a party to a telephone call between my wife and her brother, and the whole of clip six is exactly that.
