That said, I don’t know what I’d do if I came across a raft of 120 people. I’d certainly be wary of them, but I think I would try and provide what assistance I could safely, recognizing my boat has limited capabilities, and can only hold maybe dozen people at the very most.
A metaphor for the situation as a whole.
Your choices in such an encounter would be:
1) to render assistance and be swamped and/or hijacked, in which case you may end up swimming with the fishes yourself (as you said, your boat has limited capabilities, and you're taking up valuable space/food/water).
2) sail on, giving them a wide berth.
Essentially, those were the choices of the protagonist in the German movie discussed in another thread here, with some additional complications which arose from her indecision between choices #1 and #2.
You are saying that your choice would be #1, but from the clauses conditioning your assistance on the capabilities of your boat and the realities of Med crossings by migrants, I suspect your revealed preference would be #2.
Sure, if you came across a small dinghy with a handful of women and children, you'd render assistance. What if the migrant boat instead contained many dozens or even hundreds of young men, as most of them do?
Would you do pull up next to them to explain you can only take 12?
Also, you're assuming that the quoted official is correct and truthful about the history of such incidents. Given the obfuscation of this situation by European officials and the media, I wouldn't make that assumption.
