The Congressional Budget Office (CBO), who tries to estimate the cost to taxpayers of all new laws proposed by Congress has put out its report on the PROTECT IP Act, noting that it will cost taxpayers $47 million
(pdf) from 2012 to 2016. Specifically, the CBO notes that the Justice Department would have to go out and hire 48 new people (22 special agents and 26 support staff) to act as Hollywood's censor police -- and that the annual cost will run about $10 million. Separately, the CBO notes that outside of the cost for taxpayers, the law would certainly impose costs on a variety of tech companies, by placing liability and requirements on them in regards to sites picked by Hollywood and the Justice Department to censor (you know, sites like that bastion of "piracy," the Internet Archive, which Hollywood has already put on its evil pirates list
). However, it does not estimate that additional cost on those companies, since it will depend heavily on "future judicial proceedings."
