Some idle googling and playing in Excel
Number of Police (entire UK Aug 2011) 137,000
(Source: http://www.guardian.co.uk/news/datablog/2011/aug/09/london-riots-number-police)
Total Spend on Mobile Devices
80m + 29m = £109m
(Source: NAO / this article)
Backend Infrastructure:
Max number of users per B'berry Enterprise Server = approx 2000
So 137,000 users / 2000 = 69 servers @ £5000 TCO per server = £345,000
109,000,000 less 345,000 = £108,655,000 left to spend on the actual devices
Devices:
So Device spend available per officer = 108,655,000 / 137,000 = £793 per device
Average no contract price of the newest highest end Blackberry: £440
(Source: http://www.puremobile.co.uk/BlackBerry/BlackBerry-Bold-Touch-9900/)
So required actual spend to equip 137,000 officers each with their own £440 Blackberry = £60,280,000
So profit made by whoever got this plum contract = 109m - 60m = £49million pickpocketed out of your taxes.
WTF???
