Legal assumption such as this date back to the beginnings of organized law, in this case since they were in the vicinity of the illegal narcotics it is stipulated within the law itself.I agree, it's an assumption. But until it's proven, it's unjustifiable. I'm not into confiscating items uniquely protected in the Bill of Rights based on 'assumptions', especially just because it makes good "news" and soothes the feels of the numb masses.
