You don't even need to film it, it's on Google Maps Street View: https://maps.app.goo.gl/cdyFttFsQPhpBHR48

That street view was filmed taken two months ago, when it was still warm and nice out, so tent activity would've been at its peak.

I wish I had seen your post earlier because I literally walked that stretch of road earlier this evening -- a couple friends of mine from out of town are going to the Patti Smith show at the Paramount tonight and we had drinks nearby. No tents in sight though we did encounter someone walking around with a blanket wrapped around their head. But still, one probable homeless drug addict is hardly "overrun".

It's really not as you describe... I agree things were getting worse in ~2019 and then became way worse during the pandemic, but it's much different now.
