The NYT article "Police in Suburbs Blocked Evacuees, Witnesses Report" discusses the strange incidents on the Crescent City Connection, over which evacuees from New Orleans tried to get to promised safety in Gretna. See Gretna Police "trapped survivors in New Orleans" for the more trustworthy UPI version of events, and see "Building communism under the overpass" for the original screed which the NYT article claims to confirm.
While I don't doubt that the paramedics' tale is more or less accurate, it's the "less" part I'm concerned with. What parts of their tale are true, what parts are lies, and what parts are embellished? The fact that the NYT doesn't approach their tale with any shred of skepticism tends to make me... even more skeptical.
Should I trust what the (apparent) socialists have to say? Should I trust the NYT's "confirmation" of what they say? Unfortunately, I can't do that. I'm waiting for a more trustworthy source to find out exactly what happened.
