think theyre blowing the lid off a new human trafficking opperation in Los Angeles

However, others suggest they are the work of a local homeless individual dealing with mental health challenges, as similar signs have been observed off the 101 freeway embankment near the LAPD helicopter station.

It's LA, I'd imagine it's possible it's some kind of r-slurred art exhibit

I can't imagine someone would let their trafficking victims go for nice walks to rearrange steel beams for satellite photos. Or just leave things the way they were after they had escaped long enough to rearrange giant steel beams or planks or whatever the frick that is

Also:

Never occurred to them that simply stacking those planks against the fence they could have just escaped over it…they took the time to ask for "help" 4 different ways with perfect English spellings and actually trying to escape was never an option to them?
