the cops and the judge are going to have a hard splainin this one. they go away with the first raid. but then a judge OKed then to reopen. so now they conduct a second raid and will need to explain why the city and the cops shouldn't have to pay up.
I know you both are anti-LEO, but they announced themselves (and @Burgers Allday they likely knocked on the door too), and when they got no answer, forced entry to enforce a search warrant that was signed by a judge. It's likely they were suspected of dealing drugs but in reality, I have no idea.
@Cop Watch, just because a judge OKs you to reopen, doesn't mean you can go back to doing illegal activities, and are immune from future criminal prosecution. If MPD was wrong, the owners will sue the city, but I have a feeling they won't win anything.
