bullride在回辛苦的帖子里提到：.....警察可以检查你的驾照，如果该警察临机一动，要你打开后车厢检查违禁物品就是两回事了。不过当时反正是不能拒绝的。只有到法院才可以搞警察歧视，选择性执法...（http://xys.org/forum/db/3/182/41.html）俺赶脚这说法泼有些舞蹈之嫌。
白大哥是如何对应这类情况的呢？
http://www.youtube.com/watch?v=nyokKFIecIoWithout Probable Cause to search your car or your home the Police must have your consent. You have the Constitutional Right to refuse to give permission for the Police to search.
Sometimes when "consent" is given to search your car or to search your home, the Police come upon some contraband which you did not even know was present. It may have belonged to a prior passenger or to some visitor in your home. The Police will charge you with this violation.
Since most requests for car searches are done on the highway while the Police are videotaping the stop, it is difficult for the Police to "remember" the facts any differently than shown on the Police video. The refusal of consent is an exercise of your Constitutional Rights and the video will show your refusal.
If it is possible, you may want to tell them that you will do whatever your Lawyer tells you to do but you will not consent to any search until you have talked to your Lawyer.
