How long? What if people start dying there?
start?
Given the situation in Chicago, something ought to be done about the high levels of violence there. Obviously it's bad if Trump occupies the city (pretty unlikely), but there isn't really a case to be made that doing nothing there is an acceptable response. The city of Chicago should be the entity doing something, but if they fail to act do we really just want to leave the bodies piling up? I would hope not.
Why single out Chicago, other than it's Obama's hometown?
