1. Who is John Baird?

2. What investigation did Mr. Baird order regarding airline security?

3. What prompted Mr. Baird's investigation? Be specific.

4. What security concerns are there when passengers are able to keep their faces covered? (See photo under "Background" below of women wearing the niqab, which covers their entire face except for their eyes. NOTE: Some niqabs cover even the eyes with mesh over them to enable limited sight.)

5. Muslim women who wear the full veil argue that they don't uncover their faces for anyone but their husbands or families, and then only in their homes. Do you think this is a valid argument for permitting individuals to keep their faces completely covered when passing through security in an airport? Explain your answer.
