If information is released and is not externally and independently peer reviewed (as was done with the large constrictor report) then it is not credible and should not be used.

I don't need a peer reviewed scientific report to tell me the sky is blue nor do I need one to tell me that cold wiped out most of the pythons or that they aren't going to survive much further north.
The way some people on here carry on about the scientific process it really makes me wonder how we survived as a species before science came along.
