This would be very negative for trade and so on, however . . . knocking up ALL the directors of relevant freight and shipping companies at three in the morning EVERY time their commercial resources are used to bring illegals in to the country might improve security procedures on the vehicles used and then, by simple economic avoidance of the most risky ports by the hauliers (already done, slightly), improve the protection around ports and then, by political complaints by port and local-authorities, improve national policy in the countries at the other end of the shipping routes (France, Belgium, other countries for air-travel). Alternatively, can we ask the French Ambassador to provide an individual explanation for each of the people fleeing his, apparently, dangerous and inhumane country?
