Crime mapping is expensive

Dave Hill wites in Comment is Free that the new Met Police Crime Mapping Site cost £210,000!!

Over £200k for a pretty basic google Mashup – surely not? The range of data and the level of functionality available is minimal to say the least. Particularly when compared with sites developed by West Midlands and Greater Manchester on similar or smaller budgets.
Could it be because they had to rush to satisfy their new political master? Nice work for someone.
