David Shepherd on Technology and umpiring

David Shepherd contends technology is the only answer:

"'Technology has got to be used more,' Shepherd said. 'We are judged by technology and people have started thinking that the technology is better than the umpires. That's not true: on an lbw appeal, an umpire is better placed to judge whether the ball will hit the stumps. But perhaps the TV could help check whether there was an inside edge."

This is an opinion held by a large number of cricketers, fans and even administrators.

However it is incomprehensible why umpires still loath to use technology.
