Today I read an article in Texas Monthly about how vulnerable the Houston Ship Channel is. Unfortunately it not only requires a log-in but a supersecret access code, or else I'd link to it.
Anyway, the article discusses the impossibility of securing such a large and busy port, and describes the vast storage tanks for highly unstable and lethal chemicals that surround it. But the centerpiece of the article was the writer's own horrific worst-case scenario in which dirty bombs on a ship are detonated next to an oil refinery minutes before a bank of chlorine tanks are blown up, causing catastrophic damage and mass panic throughout the region, until everyone's lungs liquefy and they all die in suffocating convulsions while trying to leave the city on foot. You know, just a little light reading over coffee on a nice sunny day. Wow. Damn. Have a good morning!
