Federal officials should consider reopening public access to about three dozen Web sites withdrawn from the Internet after the Sept. 11, 2001, attacks, a government-financed study says, because the sites pose little or no risk to homeland security.

The RandCorp. said the overwhelming majority of federal Web sites that reveal information about airports, power plants, military bases and other potential terrorist targets need not be censored because similar or better information is easily available elsewhere.
Rand identified four Web pages that might merit the restrictions imposed after the attacks.
"It’s a good time to take a closer look at the choices that they made at the time," said JohnBaker, principal author of the study, which was funded by the National Geospatial-IntelligenceAgency, the government’s intelligence mapping agency.
Advocates of open government said the report shows theBush administration acted rashly after the suicide attacks when it scrubbed numerous government Web sites.
