Earlier quoted context omitted.
If the UK population is 64 million [1] and the annual national policing budget is 3.5 billion, that's a per person budget of £54 per year. So £10,000,000 on one accused person is the equivalent of the annual policing budget of 185,000 people. Spent on one person yet to be trialled. You'd have to say this is a disproportional response. Why? [1] https://www.google.com.au/search?q=uk+population
That's not a reasonable argument, though. You can't generalise police spending over the population because criminals make up a relatively small proportion. Is it a disproportionate response then to spend £10m on one guy? The fact that he's not been tried yet is irrelevant – there's a warrant for his arrest, and for a pretty serious crime. I struggle to see what the alternative would be.
1 in 185,000? That's not criminal it's targeted.
