I guess maybe I'm just too paranoid or cynical (or both), but isn't there a strong possibility that the drugs found were placed there after the raid? As we have seen in a variety of locales, this is not an unheardof practice.
I also agree with paratrooper; dynamic entry, full-auto weapons, shots fired, all in a situation the hut-hut-hut guys simply did not understand. An obvious recipe for disaster. Plus, how many homeowners have been barbecued for a mistaken identity shooting? Yet another double standard.
