The Umar Akmal decision was one of the most horrendous DRS calls ever. Steve Davis give yourself an uppercut
That was a shocker. Incomprehensible to me that the batsman didn't get the benefit of the doubt. Not the first highly dubious decision based on snicko recently either. Ronchi was given out in similar circumstances in one of the pre-Cup games.
Without hotspot for corroboration it's a pretty unreliable bit of 'technology' imo.
