the local radios have been carrying news on this, including minnesota public radio which has actually been fair and balanced.
Early pre 6am morning reporting (prob before official voices could squeltch it) included the facts that
A. It appears the address on the warrant was wrong, that's how they ended up at Khang's house
B. The reliability of the confiential informant is being checked as well.
here is somethign similar

There was also an incident where a minneapolis cop ran a red, did an illegal Uturn ran up on the sidewalk a bit, and almost hid a pedestrian, who flipped him the bird and spit on him, so the cop got out and started beating him until someone called 911 and other police showed up and pulled him off.
I won't go out and say that there is absolutely no reason ever for a no-knock warrant, but such warrants should not be handed out just to help the cops preserve evidence. They should only be given out when there are hostages involved, or if the police truely believe there will be a serious gunfight and need the element of suprise. Then of course these warrants should be double and triple checked.
Second, this is more CI's lying and making up false info to lessen their own charges, and getting away with it my gut is telling me
and yes, it doesn't say much about the minneapolis police department, but then that is no suprise. They are a crazy bunch. Check out this incident where one Minneapolis cop bazes away at another cop basically because he is asian.
