I have noticed a creeping tendency on this forum for posters (on both sides) to question the expertise of their opponents.
e.g
"In response to one of my posts yesterday Davel told me that several posters have an elementary knowledge of dog handling and the use of EVRDs.
In my professional world having an "elementary knowledge" would mean one had attended at least one basic awareness course on the topic presented by an expert. I incline to the view the posters to whom he refers have not attended courses but have Googled or have read a Janet & John's guide to EVRD's "

This is an internet forum, for heavens sake. Its a discussion group, not a court of law or an expert witness program. We are none of us experts in the subjects under discussion (Portuguese law, forensics, VRD, police procedure etc etc).
However, we are all able to debate intelligently, have opinions and draw conclusions based on experience, google, logical thought, discussion.
As soon as the debate turns from force of argument and logical reasoning, mixed with (hopefully) good natured humour and banter, to "what are your qualifications for saying that" we might as well all pack up and go home.
