I'd suggest you have a look at how policing is done outside of USA. A raid on someone's home is almost never justified - it would take highly exceptional circumstances to make a "normal" police force perform like that.
Raids are common in almost every European country - which in general have "normal" police forces - where the police believe someone might destroy evidence.
Nonsense. There's a world of difference between a couple of cops knocking on your door and a full squad of fully armed, fully armoured militarised faux-soldiers busting down your door and threatening to shoot you, your family and your pets - and often following through on those threats.
