Every family is subject to be searched. Why the suggestion that military families are left alone? Come on! I doubt these people had loaded machine guns aimed at them. I have been stopped while driving to work in rush hour traffic ----IN UNIFORM!! So, that deflates your theory that military members or their families aren't prone to be harrassed. How sensitive should they be? See the link to the CG statistics on how many pounds of drugs and smuggled people they find every year. Here are the links again, in case you missed that one: http://www.uscg.mil/hq/g-o/g-opl/Drugs/Statswww.htm and http://www.uscg.mil/hq/g-o/g-opl/AMIO/FlowStats/USCG.htm
People are responsible for their individual actions. Even if they are following orders. If they don't like the order they can do something else for cash or they can serve time in a prison. That said those out waving machine guns at people, for no other reason but they are there, and they want the money, should know in the back of their mind that some other guy is waving a machine gun at his grandmother.
The war on drugs is basically a war on freedom and a devices to employ government workers. Follow the money, right from the paychecks of non government workers right into the pockets of the government workers
