I can't find data on the costs on Colorado, but wouldn't be surprised if it's not also way up there. These systems aren't cheap. I do find data showing that several cities are making money from the systems, including Denver police who said theirs pulls in about $721,000 in 2010. Studies as to whether they're working in Colorado are mixed and nationally they are the same - some say they work, others say they don't and still other say they cause more harm.
