Realistic Space Pirates in Hard SF

[GTOM]

No, but stuff will decompress.

Then what? Even if the crates scatter, it is easy to capture them, leaks can be sealed easily, cargo ships usually unmanned, but if an armed cargo ship is manned, and the crew don't have spacesuits and die... the pirates get over it.

Capturing a space station while not dooming the people isn't that easy, I described, that the assault boats have plasma cutters, melt their way in, then seal the leaks with some kind of metallic foam.
