If there's one thing most decent humans can agree on it's that animal cruelty is pretty despicable.
Nothing seems to galvanise the public quicker than an ill-treated furbaby: we launch mass protests to free beagles from science experiments, organise petitions to ban battery farming, donate tens of thousands to the SPCA in our wills, and start up our own animal rescue centres.
Now appearing in the headlines is Cecil the lion -- the majestic beast shot on Zimbabwean protected land by US dentist Walter Palmer.
The online retribution was swift and merciless. Anyone with access to a keyboard was calling for Palmer's head on a platter.
Understandable. But a Facebook post from an American friend caught my attention: why does a lion inspire such extraordinary unanimous wrath, yet the deaths of countless unarmed black people at the hands of the police inspire ambivalence at best?
