Everyone is a victim of this stuff, not just the upper class. Poor people getting to work having their car windows smashed multiple times is a serious issue. But the constant drumbeat of property crime, dirtiness, and leud acts in public it gets downplayed because the murder rate is less than it was during some prior horrible time in the city's history and people feel some need to defend their own city (and the particular sort of politics it's famous for).
Yep, people haven't been complaining about murders. It's almost entire the property crime and general lawlessness. This murder just gave people the opportunity to whine about the plight.
