Why in your opinion the prostitution & robbery had doubled in NYC, only in these 2 months?

I was reading the world news today morning as usual and this story caught my eye...

Specificaly it's happening in Jackson Heights region in New York...

Sidewalks filled with h*es, prostitution happening in public, plus the robberies have been done easily during the day, so why did this region had transformed so fast from a clean safe area into a dangerous filthy area?

Hope that other places won't follow the same steps as this region...
