I should say that I'm very pro-business, and I think Mr. Chopra is just taking advantage of an opportunity. It is possible that private enterprises would demand these scanners in an alternate world. In that case, however, he would have a smaller profit margin and full liability for any ill effects. What we have in the case of the TSA is moral hazard: all profit and no loss for Mr. Chopra.
