Don't be silly. If you genuinely mean that, to say you're not a very nice person would be an understatement. So if you got a job on border patrol, and if the UK introduced a policy of 'shoot to kill if they enter our waters', you're saying you'd be fine with that? Yes predominantly men but also women and children. You'd be fine in your own soul to kill them? And don't say 'I said shoot the boat' cause shooting the boat would very likely mean death for many/most of them.Dissuade you say? What should happen is that these boats get shot to smithereens like the invaders they are. That will dissuade others.
