if not paying attention while walking is a crime... then following same logic, shouldn't walking drunk be a crime too? especially if you consider that walking drunk is actually a pretty dangerous activity according to U of Chicago professor, Steven Levitt ->
"LEVITT: For every mile walked drunk, turns out to be eight times more dangerous than the mile driven drunk. To put it simply, if you need to walk a mile from a party to your home, you’re eight times more likely to die doing that than if you jump behind the wheel and drive your car that same mile."
