What do you generally call the area at the front of a building where people park cars?
There is literally one car parked there and it is a police SUV obviously there in response to the protesters given the nearby police officers. Do you have any pictures of there being an actual "empty parking lot" there?
Nobody was claiming it was a Walmart parking lot completely unrelated to the border camps.
Infowars kind of is which seems to be the primary claim the snopes article is responding to:
“The photos show an emotional AOC holding her face and appearing to cry. Her attention appears to be directed towards whatever is on the other side of the fence,” InfoWars reported. “However, a photo from a different angle shows there is nothing there aside from an empty parking lot and some police officers.”
And the others are pushing a narrative that it is staged:
Clutching her face in despair and weeping, photos of Senator Alexandria Ocasio-Cortez seemingly show her strong reaction to a horrific scene of US migrant detention. However, new angles reveal she may have played things up a bit. While quite a few people noted that there was something a bit off about the senator’s photo shoot at a border detention policy protest that went viral this week, there was nothing concrete to indicate her insincerity... until one gets a look at the massive empty road and parking lot on the other side.

Many have accused the Congresswoman and her supporters of staging a photo-op after the images, taken during a 2018 event outside a migrant “tent city” in Tornillo, Texas, went viral earlier this week.
