Well what a surprise. Dave Edgar supports the McCanns and so must now be sneered at and have his expertise as an Ex Detective Inspector called into question.
Quote from the Belfast Telegraph
Snipped...
Dave had accepted demotion to join the Cheshire police force in 1986 after he left the RUC.
But he quickly moved up the ranks, becoming a detective inspector for the second time in his career.
As a result, Dave found himself at the heart of these high-profile investigations.
Dave’s team were stumped until they identified killer Stephen Mottram through the use of controversial Low Copy Number DNA profiling to analyse single cells left at the scene.
Mottram, 40, from Cheshire, was convicted in 2007 and will serve 16 years.
Dave said: “It was a difficult and long case, and thank God we were able to use the DNA tests.”
This have-a-go hero dad, 47, was kicked to death by a group of feral youths outside his Cheshire home.
Dave Edgar’s work on the case, the same month Stephen Mottram was convicted, led to his three teen killers being sentenced to life.
Dave was also awarded a judge’s commendation for his work on the case.

This is why sceptics think he's useless. From, again, the Belfast Telegraph September 2009.
"A controversial DNA test used in the failed Omagh bomb case is the key to finding Madeleine McCann’s kidnapper, Ulster investigator Dave Edgar has claimed.
But the former RUC detective sergeant’s team will never be able to use it as Portuguese authorities will not give him access to forensic information.
Speaking exclusively to Sunday Life at the HQ of his Alpha Investigations Group in Cheshire, the ex-cop leading the search for Maddie believes that DNA tests, which can establish a profile from just a few cells, could help solve the mystery."
Thing is by September 2009 low copy DNA had been used on the McCann case.
Further how can you avoid sneering at an ex policeman who was willing to carry out an investigation having only seen the files that his clients allowed him to see.
BTW Henry Exton was an OBE and, having looked at all the files, thought there were unexplained anomalies in the McCann's and their friend's evidence.
