They didn't allege DUI or GTA so he should not have been subjected to search. Nor arrested. Having pot in an RV is not enough reason to deprive a free human of their freedom. I wish more people would love freedom more than they hate pot. I can understand hating pot, but to hate it to the point that you are willing to let the police put people in a cage. Just for having it in your possession. Not DUI, not giving it to kids. Then you got problems, our society has problems.
I am not saying this person had pot, but I heard that was the charge. I am just saying even if he or any one else did, just have it in an RV they shouldn't be pulled out and arrested for it.
