I agree with you if that is what really happened. On the other hand the whole search sounds bogus, and they should have never been in the home to begin with.
I personally think drugs should be legalized, and we should use our police force to pursue real criminals (those who hurt other people). What someone does in their home should be their own business.
I agree, except that what people do in their own home should not include assaulting other adults or harming children. (I realize that "harm" can be too elastic a term here)
