Unfortunately, much of the info in the "Protester Defense" post to Portland Indymedia is erroneous; some of the information is dangerous. [Tear gas canisters DO cause severe thermal burns! Also, any direct action eye protection must be shatter proof (against projectiles like rubber bullets, tear gas canisters, batons, etc.)] See the Portland Black Cross Medical Collective web site for accurate information:
