Reason.com reports that this consensus is cracking [1]
And the correction at the end begs a fascinating question about
whether the media should present both sides of an issue. If
99% of research says A and 1% says not-A, is the media being
misleading by reporting both views? If the media doesn't
present not-A, then is it censoring opposing views?
Actually, they published an article highlighting the different view of a single researcher (ok - he had a co-author in one paper). Note that the paper showing the decrease in violence makes no claims for the reasons behind it.
I find his argument compelling, but that doesn't mean the consensus is any different.
