Curbing the violence in New Orleans will never happen because the solutions to said violence would insult the politically correct sensibilities of too many people in New Orleans.
A man is shot in the face while holding his baby in broad daylight. No marches, no outcry form the reverends or community leaders. However, if a black man stopped on the street without probable cause to be "shaked down" by the NOPD and is found to have a weapon while on parole, well, then it's 1965 all over again. This is an injustice to the black community. Now we're talking marches on city hall.
Do you see the difference? Things will never change as long as the guilty are protected, if not celebrated. The victims are forgotten, if not swept under the rug before a tourist sees them.
