Events like this are valuable.  When I was working for Mayor Barry in DC, we did one (a bit more secularly, (which was likely an oversight - we were usually pretty good at bringing in clergy) to help set the tone for whomever would be the next mayor.  This is the kind of project that Rahm Emmanuel should have done early in his mayoralty.  Instead, he seems to have pandered tot he police and the existing racism.  Bless the new Cardinal and shame on the Mayor of Chicago (and God rest Marion's soul).
