They seem to be trying to investigate and/or expose the murder of Jeff Baldwin. (I tried a google search, both for Pittsburgh and nationally, for any dead Jeff Baldwins but found nothing interesting.)

I also see a mention of "John Guessman." Googling that name brought me here (https://kingofegypt.net/pitt-pa-smooth-criminal), which appears to be a lot of insane nonsense but definitely related to Pittsburgh, which convinces me that the guy who left these signs is the same guy who made the page. It's also called "King of Egypt" and the top of the sign says "King of (something)" so again, that can't be a coincidence. The website is even harder to understand than the picture is, but it does refer to John Guessman as a DEA agent in Washington DC. (FAIR WARNING: There is also a lot of use of the n-word on that website).

Again, the website is very hard to read/understand and there's a lot of things that have no obvious connection, but my best guess is that the thesis is that the white government (and John Guessman in particular) are intentionally trying to kill people of color (especially Jeff Baldwin).

There's also mentions in the picture of a $10 million heist, and a heist related to a drug cartel bust in Aliquippa that led to the death of Jeff Baldwin (same heist, I assume?)

Actually, I just searched again, and now I've found a Jeff Baldwin related to Aliquippa. Looks like he was an up and coming star linebacker at the high school level in the 80s. I can't find any mention of him dying or where he is now. Skimming through the website, a found a reference to an attorney John Hudesack Jr. of Beaver Falls advising Jeff Baldwin that it would be "dangerous to testify in the KKK case." I tried searching for Hudesack with and without the junior, in and out of Beaver Falls, but found nothing.

I've just now realized that the "King of" message at the top and bottom both say "King of Atiest" (at the top it's King of Atiesting". I believe that's a misspelling of "King of Atheist/Atheisting", which is a phrase with plenty of hits on google. This appears to be the author's name: "The King of Atheists" The final poster in the picture says the DEA raided The King's home, perhaps in 2019. It also gives Jeff Baldwin's weight as 280 pounds...is he missing?

Top right poster suggests a "double agent" told The King that "their" goal is to kill Jeff Baldwin...who at this point, I'm beginning to think might be The King's real identity.

Judge Brook Smith and Attorney Verdell Dean are both real people in Pittsburgh in those positions, per google. The phone number listed in the photo goes to Attorney Verdell Dean's office.

There's also a mention of Linda L Montgomery. Googling that took me right back to The King's website, where he says "Linda L Montgomery will never see her son if she violates any law of god." There are some photos too -- some I think are Janet Jackson, but some of them could be Linda. I wonder if she's The King's mother. Linda, Judge Brook Smith, and Attorney Verdell Dean are all listed as people who know the truth, per the picture.

That's as far as I can take it. I don't know why this is what I decided to dive into at 1 AM before a workday, but I enjoyed it.

They’re connecting people and events but without a thesis statement it’s all random nonsense. I mean it was always going to be, but you don’t even get a chance to see where it’s coming from

Fair.

If I had to write out that list it would probably wind up looking something like this.

But what about freedom?

This^^ 🤣🤣🤣

Just tearing them down and throwing them away works too

Worked in WPIC for years. This is pretty standard behavior for a fair amount of our paranoid schizophrenic friends who aren't on meds.
