The ePetition system can be used to request parliament to gather and publish information. For example this link on the No. 10 ePetition site, shows a request for a study into the economics of legalising drug use . I can see the benefits of requesting such studies, but their may be genuine difficulties in getting the information because of the problems (impossibility?) of gathering it. In this case it may be very difficult to set up a small scale experiment, as cheap, licensed drugs in one location would attract addicts from other areas, with various social consequences. Other types of study may be more successful and may already exist without the knowledge of ePetitioners. It would be useful for links to this information to be added to the ePetition site.
"Can we ever have enough information?" Using ID to rationalise the release of information under the Freedom of Information Act is one way of prioritising requests that may prove to be very expensive and are currently often instigated by individuals and journalists.
