I've been reading comments from Europe complaining about the high handed way the Americans shot the pirates, some whom are seen as poor fishermen out of work and needing assistance. That the poor fishermen were pointing guns at the captain and demanding millions of dollars in ransom, not gift certificates to McDonalds, doesn't seem to faze the critics.
On the other hand, even US military brass have acknowledged that shooting the pirates will up the ante in future scenarios. So while I don't feel sorry for the pirates that got shot, I do feel some concern about the next hostage and the circumstance he will find himself in.
But bottom line, maybe we should revive keel hauling or those cute iron cages with rotting bodies that used to greet seafarers arriving in British ports.
