Let’s see if you can work this out James.
You’ve already posted report of 4 deaths crossing the channel today. You and I both know that’s just four in many hundreds.
The migrants are obviously aware of the risk of drowning.
So you think you can come up with a deterrent to dissuade people who are already willing to risk their life to make the crossing.
Or is it, as I suspect, you haven’t thought this through?!
