I fail to see why 'tit for tat' responses is going to help the situation of delays and difficulties at US Immigration. All it will do is not strike at the people who cause the problem, but at completely innocent airline US crews and passengers who will be the only people affected. If anything it will only escalate the problem rather than go towards finding a solution. There is a problem with US Immigration officials and officialdom- tell me again how making life hard for ordinary Americans will help?
