Image and Video Sources from LGSEO Tour

Hey so I've watched videos of the LGSEO tour a million times, and I'm super interested in the origins and meanings of all the images and pictures they use in the tour in the background for all the songs. A lot of these images seem to be obscure police cases or religious or cultural imagery from decades ago. I'd love to make an in-depth video essay about all this. So I just wanted to ask if anyone knows where I could find the sources to all these things? Especially where I can download the images or videos. Or where they possibly could be from? Any info is more than welcome! Thank you all :)
