Born and raised in California. I haven't been to New York, but I have driven across the country before (but not for quite some time).

Yes, but it's less pronounced where I live at least. I think New York has possibly had some it's cultural identity subsumed by this, but that's is not entirely new. There are portions of the country where historical occurrences from much further in the past inform the mindset of the population (at least a little) to this day. Such as the civil war.
I still think it's worth point out though, as urging people to be aware of suspicious activity everywhere is at best pointless, and possibly counter-productive. Either you can't relax, or you get a false sense of security about situations where heightened awareness is actually useful (such as large gatherings of people). In that respect, it's security theater.
