I'd be interested to see the crime stats from the last year to today - from the sentiment I've seen on social media it appears violence has been increasing since the Jul 2 your source article was posted. Add to that they slashed the police budget on Jul 1[1] I think the OP may have a valid point.
10 months of increases does not negate two decades of decreases. And that's even assuming there is an increase, since "the sentiment on social media" may very well be incorrect as is the comment purporting a more dangerous NYC.
