I stand corrected.
3,000 windows/year equates to about 12 windows/working day which, sadly, is obviously no where near enough.
I usually have little sympathy for Metro and their antics so far as customer service is concerned but in the case of vandalism I do have some empathy as it seems that despite what they and the Police can do that in so many cases the courts are on the side of the bad guys .I do wonder, however, how current the 3,000 windows/year is as the clip appears to be from 2011. Perhaps the number replaced has increased, dropped or remained static?Perhaps the film would help but from the video it seems as it is easily peeled off.To me, the only solution seems to be undercover/guerrilla tactics by the police and zero tolerance by the courts. The first may well happen but the latter never.
