Do you have a question about your civil liberties?

In this week's Liberty Clinic, James Welch tackles Shadowfirebird's question about what sharply pointed objects can be carried without arousing the suspicion of the police. Gman81 also had an interesting query about police powers to set up random blood-testing stations. If anyone has had any personal experiences of this, please do share it in the thread below. For those of you who haven't visited the Liberty Clinic before, each week we invite readers to post their civil liberties and human rights queries. Whatever they may be, share your queries in the comments thread below, keeping your posts as succinct as possible. And don't forget to check next week's Liberty Clinic to see whether your question has been answered.
