The last sentence is really the icing on the cake - "Police said no arrests were made in the subsequent raid at the upstairs apartment."

So, apparently their information was faulty on multiple fronts.

I think what really galls people the most when they hear of these things happening is the fact that the jack-booted...er...um...cops display such an incredibly arrogant and unapologetic attitude. They make it seem like it is the fault of the people living there, instead of their own incompetence.

Either that or their stupidity gave the occupants of the right apartment the opportunity to escape.
