Its all b******s and we know it
The rise in 'phone crime' was due to insurance companies not paying out until a crime ref no. was provided, the fall is due to phones being categorised as 'household' items and not needing a crime ref no. to payout.
The 'Phone Crimes Unit' will be disbanded unless they can
a. show a rise in crimes.
or
b. they can lobby loud enough.
What we really need is a pin code in designer jeans (anybody remember them) to stop muggers leaving you standing there on Clapham High St. trouserless clutching your brick sized vodaphone.
