For some very quirky reason, some people get a big ego boost by walking their pit-bulls up and down the avenue. I think it give them a feeling of euphoria and power.
They are not concerned that the four legged Demon of Death, the # 1 most dangerous dog on the planet, kills as many as 22 people a year in the USA alone; many of them being children of the owners.
I am not suggesting that ALL pit-bulls be euthanized but I would recommend that they should be restricted to living in rural environments and outlawed from the cities where they are a great danger to the public.
Knowing the mentality of pit-bull owners, I can understand that they are too thick headed, even with the history of the beast, still maintain that their four legged meat grinders are NOT a danger to society.
