In recent months, Australian investigative crime podcasts have prompted arrests, reopened police investigations, and cast new eyes over long-dormant case files. In December, Chris Dawson, the subject of The Australian's Walkley Award-winning podcast The Teacher's Pet was arrested on a charge of murdering his wife Lynnette Dawson. In November, the police investigation into Maria James' murder, examined in the ABC's Trace podcast, was reopened.

But with the heightened attention and official action, more and more commentators are worried about crime-as-entertainment getting too big: could it affect trials, and is it damaging to the victims?
