What is going on here that no one talks about it

A couple of months I saw a post on X that typed the coordinates

34°03'17.8"N 118°13'32.2"W

And looking it up it’s a bunch of Help signs with garbage I would say, some says Traffic, Terrorismo, LAPD and help all over the place, also the place is located next to a container place and a train track next to it what is going on there and why not even locally you hear about it I live 10 min from it and not a single time I see something about it
