I am rethinking my original comment. Initially I thought that if they knew there were drugs in there and were chasing some drug dealer, it may be OK, but in rereading the article and some of the comments, I am coming around, that it is indeed too much power for the police and the SCOTUS is wrong in ruling this legal.
It is scary, isn’t it. As someone pointed out, this overrules one of the freedoms in the Magna Carta. Which means that medieval Englishmen had more rights than we do.
