The checkpoints U.S. citizens pass through upon returning to the country vary greatly in the depth of the checks and the time spent. The simplest involves simply walking past the border guards who may or may not ask border guards who may or may not ask you your citizenship. The other end of the spectrum requires that you put up with long waits in airports where you have to line up with hundreds of other passengers while each person is questioned and must produce a passport to be scanned. Would you welcome biometric information on passports if it would speed the process, or do you think that the disadvantages of the reduction in privacy, caused by biometric information, outweighs the advantages of better security and faster border processing? Explain your answer.
