Chicago Homicides Reach 400 This Year, City Turns To Twitter For Ideas To End Violence. And 117 of those victims this year alone were under the age of 21.

And in her home town of New Orleans, we've had 174 murders, most of which are gunshot deaths and in Los Angeles, there have been 512 homicides recorded for the year, and 75 percent of those deaths resulted from gunshot wounds.

HARRIS-PERRY: These are the gun related homicides that get treated as routine -- tragic, but expected. And yet, they need to be included when we talk about Newtown, CT, because their victims are just as real.

The Nation's Ari Melber followed with this:

MELBER: So while we understand exactly how terrible this is and why the story of it and the way it happened is so dramatic and we're rushing to it and the President's speaking to it, it's also true as a policy matter that if 27 people dying is something that connotes the President's attention or our attention and action, well then every day is this day, as you were saying and all around the country.

As Michael Eric Dyson noted, President Obama did bring up those in Chicago during his statement following this most recent shooting and made this important point:

DYSON: The reality is, we've become accustomed to believing that little black and brown kids and poor white kids in various spots across our landscape are doomed to this kind of violence by this... we are surprised it happened here. It's not supposed to happen here.

Which means by implication, that it's supposed to happen there, in Detroit, or Oakland, or California, in LA and the like. And I think that's the tragedy here.

As Harris-Perry rightfully noted a bit later in the segment, she just wants the same level of outrage when you're seeing these kids in our inner cities having their childhoods taken away from them with the violence that they are growing up around as a part of their daily lives as we've seen from these mass shootings that garner so much national attention in the media.

I hope if there is an ounce of good that comes out of this shooting, it's that conversations like this one are more common where we're talking about what we can do to put a stop to gun violence along with a host of other topics that are all interwoven with the same subject and those are not just gun control and gun violence, but mental health, providing adequate health care for all of our citizens, education, poverty, our social safety nets and just what kind of country we're allowing way too many of our children to grow up in.
