Well I'm no mind reader, but I'd venture a guess that anyone that really wanted to complain would be talking to a lawyer and not ruin the case discussing it on the internet. I read the ACLU is doing some investigating of its own.
Sad situation either way in my mind. Either the residents were to scared or submissive to argue, or a case will go to court and they'll lose on the exigent circumstances grounds. The failure of LE to locate the subject during the search almost guarantees they'll require more personnel and equipment, and less Constitutional restraints, to be successful "next time".
