I have no real problem with house raids as long as it's the right house and they get some BAD guys.
A high school kid selling pot to friends does't warrant this kind of raid....When I was a kid and the police knew you were selling pot they use to park a crusier in your driveway or on the street in front of your house and sit to let you know they knew what you were doing.
As far as the big dealers go they went after them.
Police abuse is very common in our land.
