Bigbrotherwatch reports here the results of some Freedom of Information requests that show how often UK police request access to someone’s personal metadata. The answer is lots.
Between 2012 and 2014, 733,237 requests were made. That’s about one every two minutes. The report says that 93% of these requests were granted and most forces made requests more frequently over time.
It’s worth noting that this is all before the current government’s proposed Snooper’s Charter, which will make everything worse.
