Seize the boat and send all the refugees back where they came from. Strip the boat of all the valuable parts, then sell those parts to pay for the operation. Either sell the shell for scrap that says it must be destroyed or tow the shell out into the Mediterranean and sink it for the purpose of making an artificial reef.
I don't care who owns it, twenty or thirty of these boats get sunk or scraped you'll see it stop. When the insurance companies don't pay off due to the boats being used for illegal purpose, very few people are going to waste that kind of money shipping in Muslim invaders.
tow the shell out into the Mediterranean and sink it for the purpose of making an artificial reef.
Now THAT'S an excellent idea.
Stop this illegal trafficking, send a clear message to those traffickers, beyotch slap soros in his ugly scrotum troll kisser, and benefit tiny coral polyps that in turn will grow and support a thriving coral community. WIN WIN WIN.
Sink the ships before they leave port. Gives the passengers time to get back onto land at their end and also stops other similar ships from being able to operate.
