Here's a link to what appears to be vets going to the Vietnam Memorial and breaching the barricades there.

I can't personally say for certain, as it has been some decades since I was there, but I don't remember any low fences at the entrances to the ramps at the memorial, so those likely are NPS barricades.

I went a few years ago..it’s an open air memorial, no entrance/barricades etc...
