Wow, this is some seriously impressive forensic work. Steve is going to dig this… :-)
Three men were accused of selling firearms to South London gangs. At their 2012 trial in Croydon Crown Court, the prosecution played the jury a recording, taken undercover, of the trio allegedly arranging a sale. But the men’s lawyers claimed that the recording was a fake, and that the police had fabricated it by splicing together clips taken at different times. To prove that the evidence really was authentic, the Metropolitan Police turned to a technique called electrical network frequency (ENF) matching.

So much so that I am putting together a presentation on this for a class upcoming on 20230306 when we talk about Maxwell’s equations. Absolutely excellent. Many thanks for this!
