我覺得石凳的界定不是絕對的，譬如说出於特定的表達需要，鐵鏈的形象就可以。

但人不可能永遠衹有特定的表達需要而没有一點別的 , 例如憐憫，so I am guessing stonebench was just irritated when some people ALWAYS and ONLY used this image for their own purposes.

Regarding the case itself, it seems that the whole country has been talking about it. Common people even succeeded in helping to locat e a few candidates for the victim's true identity.  Linmu's poem seems groundless to me.
