Video: Justin Langer clearly edges to slip but doesn't walk

It does not get any blatant that this! Justin Langer almost middles the ball to the slips, and refuses to walk! Commentators then proceed to put some part of the blame on Sri Lanka for not appealing enough.

Further conversations between the commentators is about the legitimacy of the catch, but even that looks clean. Poor cricket overall.
