[MCU] Why were no New Yorkers alarmed to see Loki in New York again just walking around?

It was only recently (8 years reeeeee) that Loki invaded the city and killed hundreds of people. But in Ragnarok those two girls ask Thor for a selfie and completely ignore Loki standing undisguised right next to him. What gives? I'm sure if Osama bin Laden were to stroll through New York right now someone would object.

You ask an average New Yorker, they'll tell you it was the Chitauri that invaded, not Loki.  They saw a bunch of weird aliens flying around blowing shit up, not a suave looking Asgardian.   
The authorities obviously know Loki was in charge of it all, but they had no real reason to share that information, so they didn't.  New Yorkers have no real idea who Loki is or what he looks like, which is why the girls ignored him.
