I grabbed the original post because someone had forwarded it to me as a blind item and I googled it to the Socialist Worker.
There are two things to say about that:
1. There is corroboration from other EMTs on a non-political EMT site.
2.
AFAIK, the key motivation for the "Socialist Worker" would be to absolve local authorities and blame the Bush administration. So the thrust of the article seemed credible -- despite the source.
