I am a regular on activistcash.com. There's some really interesting material there. Been reading it since the site went up. Another good site is the Americans for Medical Progress site.
I also like to read the transcripts from the Animal Rights conferences. The so-called "mainstream" AR groups are having a hard time reigning in the radicals in the movement. Groups like the HSUS are trying to distance themselves from the more radical, since they depend on donations from folks who just think they help animals. But, if you read enough, you'll find the leaders of the HSUS, PETA, ALF, are all the same.
Are you familiar with the reporter who infiltrated ALF years ago and, when caught, was burned badly in retaliation?
There's lots of material out there that can expose a lot of these "animal protection, environmental protection" groups, as the media likes to refer to them.
The suspects in the case - Chelsea Gerlach, Kevin Tubbs, Josephine Overaker, Stanislas Meyerhoff - may be notably short of sympathy in the Vail area, but not everyone is ready to convict them.
One Web site - ecoprisoners.org - provides a list of many of the suspects along with information about contacting them and items they've requested while in jail.
