"Waiting for the comments about how things were worse in the 80s."

You seem to want to have that fight, it was also worse in the 90s as well if that makes you feel better? Not saying that gun violence isn't bad anytime but things can be bad more than once. One does not exclude the other and helps for a larger historical context. I would say knowing the history of crime and violence in the city makes it more important then ever to fix it and get it right, not to sweep it under the rug.
