I'm not from the hood, can't speak in these specific personal terms. But what I can speak on in broader terms is that it always seems to be related to concentrated poverty, and the historical legacies of all these Midwestern cities have left some of the largest urban poverty pockets in the USA. That's why crime in the Midwest is generally up there with the South and worse than either coast.
Like the guy from California who said he didn't even know KCMO got down like that, for whatever reason people from each coast seem to equate Midwest with rural even know many of the biggest and baddest hoods in America are contained in Midwestern inner-cities. They don't take a look in the mirror and realize that Watts is only a relatively tiny chunk of Los Angeles but the North Side of STL struggles to an even greater degree and contains almost half the entire city's population. People from California especially, tend to really underestimate the Midwest when it comes to this kind of thing (see that legendary "Is San Diego Even Hood" thread), and I know it's pointless to stage city street cred contests but when there are constantly tremendous misunderstandings of reality, you've got to let them know.
I don't know as much about Kansas City as I do other Midwestern cities, I've really only been around the Negro Leagues Museum and then the freeway out by the stadiums. I know the city is pretty much a tall and narrow rectangle, with downtown at the north edge of that rectangle, and that the rich people live in the hills west of downtown towards the Kansas border. Now where is this "East Side" of Kansas city, it can't be out by the stadiums can it, b/c when I took in some games there it seemed like it was out in the burbs with how low the population density was. On this map, where's the East Side, where are the really concentrated pockets of violence?
