I heard this on the news this morning and I'm horrified but not surprised. The cases included murders and rapes and I really wish we could see the breakdown of the nature of the cases cross-referenced with the nature of the "loss". Entirely unsurprisingly:
"The BBC study found around one in 20 prosecutions by the Met had been dropped as a result of missing evidence between 2020 and 2024.
By comparison around one in 50 were dropped across England and Wales.
The Met said the number included situations where police could not find an expert witness or were not able to obtain a required medical statement and to suggest it was simply down to lost evidence was misleading."
Isn't it convenient that the same coding covers both types of situations...
