Farr told the committee that anything between 500 and 1,000 communication data requests could be submitted for an average murder investigation in the UK. He further explained that criminals would use multiple comms devices and, for example, regularly ditch mobile phones to avoid being sniffed out by police or spooks.
Bear with me I'm having a bear of little brain day and my figures may be wildly off
OK according to http://www.murderuk.com/misc_crime_stats.html
We are averaging around 767 murders per year over the last 10 years
Lets assume we average 750 communication data requests per murder
That gives us an average of 575250 communication data requests per year
Lets be generous and assume these are for separate individuals
Lets be even more generous and double it to soak up anti terrorist and other related requests so we get 1150500 requests per year
According to the ONS http://www.ons.gov.uk/ons/rel/pop-estimate/population-estimates-for-uk--england-and-wales--scotland-and-northern-ireland/mid-2010-population-estimates/annual-mid-year-population-estimates--2010.pdf
the population of the UK is around 62.3 million, lets be generous again and round that down to 60 million to cater for the very young, the very old and the luddites who communicate by waving flags
Divide one by t'other and you get 0.019 requests per person who communicates via any monitored means in the UK
This somehow justifies the expense and destruction of civil liberties involved with the blanket monitoring the communications of 60 million people ?
Lets be even more generous and say there's going to be a sudden increase in the number of requests for reasons entirely unrelated to wild speculation, fishing expeditions and corrupt officials digging dirt for pay and say there's going to be a nice round 2 million legitimate requests a year
We still only get 0.03 requests per person even with such a massive increase in the number of requests
How exactly is this justified financially ?
