MILITIA GROUPS PATROL INTERNET Like activists of all stripes, extremist militia groups have their own corner of cyberspace. Active for years on bulletin boards, they've migrated to the Net. A quick cruise finds Web sites celebrating guns in color photos, quoting Revolutionary-era patriots such as Patrick Henry, offering digitized scathing editorial cartoons and articles condemning the "massacre of the Branch Davidians." The on-line Journal of Patriotic Justice in America critiques media coverage of militia groups (http://weber.u.washington.edu/mcdaniel/). Despite reports linking the Oklahoma City suspects to a militia group organizing on the Net, Mike Godwin of the Electronic Frontier Foundation says that "if you actually look at the bombing, fertilizer played a greater role than computers did. "Before (PCs), they used telephones. No one thinks the phone is any more threatening because the Michigan Militia uses it."
