Seriously, if he had blood dripping from his hands, he should
have followed the path taken by Mike McCrea to VIC. At least he
could still save his life if he did so. Also, Huang Shuying's
behaviour and previous criminal records suggest that she isn't what
she seems. In fact, one NTU professor found her dodgy, if you
recall this
discussion.
It is possible that there is more to the case than meets the eye. A
number of questions still remain unanswered. Who knows, the real
killer could be laughing away at the verdict right now. 
What are your views? Is Ah Hao really innocent and been made use
of, or is he so thick that he doesn't know that the law has some
loophole?
