Three Points, ref all of this:-
1) If the Migrants can find out where to meet the Smugglers, to pay for and arrange transport, why cannot the French Police?
2) Allowing the Migrant Boats to enter the water, with passengers, must contravene the SOLAS agreement signed by France, which deems it to be illegal (unless strict safety standards are met)
3) The French own the water, as far out as the middle of the Channel, and should be ensuring the safety of everyone on it.
