Anyone can post on there, but that is more of an opinion that an explanation or factual statement.
For instance you need to foot ladders now, but was that always the case? So, nothing unprofessional about unfooted ladders untill very recently.
Also the figures are unsourced (A &E stats for example) and are wrong.
What is unprofessional is trying to pass subjective opinion off as objective fact.
WW- been sent some proofs- want to see?
