To the more deranged parts of the American left, everything is evidence for their narrative.

For example – whether temperatures rise or fall, it’s all evidence of man-made global warming.

And a couple of New York police get killed by an apparently deranged man angered, according to his social media postings, by the Brown and Garner killings?

Why naturally – it’s the guns’ fault.

No, really – there’s a crisis not to be wasted here, for the Left.  To Big Left, this is yet another chance to warm over gun control.

As if more laws would have saved those two cops.
