Roger Daltrey agrees. However, Roger does not question -- as I do -- why nobody's called in the hazmat team already.
After the credits, a biohazard-suit-wearing person walks into the house, and I think for a moment that we just might see something approximating reality. Then I see that it's Horatio in the biohazard suit, so unless he's also heading up the hazmat unit -- not entirely out of the realm of possibility, given this show -- we're apparently not going to be bringing them out to contain a cloud of poisonous gas. After surveying the living room, which is ankle-deep in debris, Horatio decrees that they'll find the source of the poison gas when they find the body. He and Speedle head toward the back of the house. There's a third person there with him, but the camera angle is such that I can't tell who he or she is. So let's just pretend they're not there for now.
Horatio and Speedle head toward the kitchen, which is a food-prep nightmare. It's too bad these occupants were too depressed to properly keep house. We then see poor dead Rudy on the floor. Speedle crouches down and notes, "Foam around the mouth; lack of pallor." So there's a lack of paleness? That seems odd for a dead person. Whatever. Horatio's beginning to put the pieces together, noting the obvious chemical residue in the sink. Speedle says he'll get the Drager, a magical device that crackles and pops as it's waved over the sink. Horatio tells us why: "Nitric acid -- 1800 parts per million." Speedle looks up fearfully and says only, "H?" My God, that's more emotion that he's showed in the last three episodes combined. Horatio explains Speedle's fear to the rest of us: "One hundred parts per million is fatal." Then he flashes back to the events of seven minutes ago: "Chemical residue plus sunlight created fumes in a closed environment, slowly accumulating deadly gas." Then he makes the decision to finally evacuate a one-block radius, what with the house being in danger of blowing up and releasing more deadly fumes. Immediately after Horatio says, "Be careful -- one spark and this place can go," Speedle drops some glassware. He's going to need to change that biohazard suit he's wearing. If I'm watching this scene correctly, then what's happening is this: having established that the house is effectively a giant gas bomb, Horatio and Speedle elect to hang out and collect glassware as evidence, since, you know, the hazmat team isn't around to clear the area for safe evidence-gathering later. Speaking of which: where is the hazmat team? This is Miami-Dade; it's not like they've never faced the problem of drug manufacturing before. Even desert outposts like Temecula, California, have hazmat teams -- how is it possible that Miami's meth-lab protocol begins with the sentence "Call Horatio Caine over in CSI"? ["I believe the sentence fragment 'Caruso's agent' might answer that question." -- Sars]
