Man-eating croc in Australia

I am just wanting to check my email at msn, and I found this interesting news about Suspected man-eating croc .

I remembered about a python tried to swallow the man in the rubber estate. Yeah this is local news that happened in Malaysia. The python was shot to dead in the end. It didn't manage to swallow the man.

Do you know why the python failed to swallow the man? It's a grown man that its trying to swallow. It was the man's shoulder that blocking its way.
