We get the figure for total theft from the Retailers Association again, with a similar lack of detail as to what it measures and how, but now without even the estimate of what proportion of it is shoplifting vs theft by staff that was provided in May. Again there is a set of high-profile or high-value examples given, but now two of the five are from other countries.
The other change is that we now are told that prosecutions for shoplifting have fallen by 20-25% over the past four years, but there is no information on how this relates to the Retailers Association estimate — do they think theft has gone down, and if not, why not?
