All of this is nice.......but its really very simple.....police officers react to STUPIDITY.....its the first clue........and driving under the influence of either drugs or alcohol is #1......stupid and it SHOWS in how you drive....#2....you can KILL other people with your stupidity..........I think stupid along with smelling alcohol or mj should be enough probable cause for the officer.  Stupid people do pot.  Stupid people drive under the influence of either.  Ask any police officer about stupid.   If you want to be stupid, do it at HOME, not on the street where you can potentially harm or kills someone else.  Someday we are going to get rid of all LIBERAL JUDGES and go back to common sense in this country.
