Most people would (correctly) say its only certain PARTS of Chicago, Detroit, and...well...never mind...New Orleans just sucks.
Can't say I am surprised. No matter what Chicago tries it results in total failure and further record breaking loss of life.
Quite literally some of the most dangerous cities on the planet are right here in the US, Chicago is one of them (as well as St Louis, Detroit, and New Orleans.)
It's pretty accurate to quantify this as predominately a problem in several distinct neighborhoods on the West and South sides.
But even then, it's still an embarrassing blight on the city and a tragedy to those in those neighborhoods.
And despite the segregated nature of the problem, there still is some (perhaps relatively insignificant) bleed-over into other neighborhoods, though that's generally property crime but may still be of a violent nature.
The segregated nature of the violence is shown by Chicago ranking around 25-30th of large American cities in terms of violent crimes per capita. Chicago's huge size plays into the many violent acts in terms of quantity, whereas in terms of per capita it ranks substantially lower. That's not to say being '25th most violent' is a good thing, but Chicago being safer than Houston, Minneapolis, or Nashville, may offer a better perspective.
I stay at the JW Marriot when I am in town for conferences. Dont really see the seedy side of Chicago life. Dont want to.
I agree...this isnt solved by silly breakdowns on law enforcement, gun control, or black and white. It is simple long term economics.
If you're speaking of the Michigan Ave Marriott, you're definitely seeing one of the nicer sides of urban Chicago. It's pretty nice by Ohare too, but it's ensconced in bland corporate suburban-like mediocrity.
I'd be careful about excursions by el to the Southside or West side; miss the Chinatown stop going south, and you're only a few stops from Englewood. Much better-off taking a cab to those areas. The West side and South side do indeed have things to offer - you just don't want to end-up in the wrong areas.
If you're ever interested in seeing the nicer residential areas, rent a car and drive north up Lake Shore Drive to where it ends and intersects with Sheridan Road, and continue going north on Sheridan Road up the North Shore through Evanston to Glencoe or Highland Park, or even further to Lake Forest and Lake Bluff if you're enjoying yourself. It's an enjoyable drive on a nice day, especially in a convertible.
In fact, before you write-off Chicago - I would challenge you to take that drive.
