After, looking at my FOI request I was still unsure about how to tighten the request. I popped into the library today to get some research for a different project and mentioned it to the librarian Chris. He said that he would take a look and help me formulate a new FOI request. We spent about half an hour doing it. I then re-sent it to the office of national statistics and the police. I hope a get a better response to last time because I really want to start producing work.
