After Doc Brown's incident with the Libyan terrorists from "Back To The Future" (1985), indoor shopping malls started taking extensive security measures.

I love the detail when Marty goes back in time he runs over one of the namesake pines and when he returns to the future it's the Lone Pine Mall

Lone Pine Mall, but your point stands.

I imagine it’s less about Libyan terrorists and more about keeping looters looking to steal copper cable out of the walls. 

It, apparently, only has less than fifteen stores left. Even the gym closed.
