On October 24, a Trump rally in Waukesha, Wisconsin, featured a very noticeable backdrop: flying prominently behind the President as he addressed thousands of supporters was not the American flag, but the black, white and blue “Thin Blue Line” flag, a symbol of the pro-police Blue Lives Matter movement.

According to the Marshall Project, “Those who fly the flag have said it stands for solidarity and professional pride within a dangerous, difficult profession and a solemn tribute to fallen police officers. But it has also been flown by white supremacists, appearing next to Confederate flags at the 2017 ‘Unite the Right’ rally in Charlottesville, Virginia.” Yale philosopher Jason Stanley has called it the banner of the second Confederacy, while journalist Jeff Sharlet has referred to it as the “anti-Black Lives Matter flag” and a “fascist banner.”

A recent fact-check from USA Today of a Facebook post containing an image of the Waukesha rally concluded that the Thin Blue Line flag has indeed been gaining prominence at Trump rallies, at least in Wisconsin. As Sharlet’s tweet above alludes to, the flag went from appearing alongside the American flag at a rally in Janesville, Wisconsin, to replacing it altogether as the sole flag behind the stage at the Waukesha rally one week later.

But can we make a comment about the Thin Blue Line flag’s prominence at Trump rallies over a greater period of time and across the country?

Over the past few months, an interdisciplinary team at Columbia University has been working on VizPol, a tool that gives context about unfamiliar political symbols to journalists covering political demonstrations. As part of our research, I am collecting data about the occurrence of various symbols in photographs from political events over the last few years on databases like Getty Images, AP Images and Redux.

While I do not yet have robust longitudinal data to definitively measure the Thin Blue Line flag’s popularity, an informal pilot study comparing images from two one-week periods in 2016 and 2020 shows a sharp increase in pro-police symbols in Trump rallies across the country.

Methodology

I looked at photographs of the Thin Blue Line and other Blue Lives Matter symbols from Getty Images’ database. Getty Images organizes photograph sets into “events.” I noted all events that came up for a search for “trump rally” in two equivalent one-week periods in 2016 and 2020. The one-week period in 2016 was Tuesday, October 18th to Monday, October 24th, 2016, and the one-week period in 2020 was Tuesday, October 13th to Monday, October 19th, 2020. Both periods begin 21 days before the presidential election in their respective year.

Results

In 2016 there were 24 events in the target period. Of these:

  • 16 were official Trump rallies where Trump himself appeared, from which I found a total of 516 photographs. There were no Blue Lives Matter, pro-law enforcement or pro-“Law and Order” symbols in any of these photographs.
  • The other 8 events were Clinton rallies, anti-Trump protests, presidential debates, and one formal dinner, from which there were a total of 118 photographs. Once again, I didn’t see any pro-Blue Lives Matter or adjacent symbols in any of these photographs.

In 2020 there were 34 events in the target period. Of these:

  • 13 were official Trump rallies where Trump himself appeared, from which there were a total of 1152 photographs. I found discernible pro-Blue Lives Matter symbols in 129 of these photographs, corresponding to 12 of the 13 rallies. In 12 photographs, I found symbols that could potentially be in support of the Blue Lives Matter movement.
  • 2 were pro-Trump demonstrations where Trump didn’t appear, from which there were a total of 58 photographs. I found discernible pro-Blue Lives Matter symbols in 25 of these photographs across both events.
  • 1 was an official Pence rally where Pence himself appeared, from which there were 18 total photographs and 1 photograph with a discernible Thin Blue Line flag.
  • 1 was a demonstration outside an early voting station in Florida, from which there were 2 photographs, both of which had discernible pro-Blue Lives Matter symbols.
  • 1 was a pro-Biden demonstration in Florida where Biden didn’t appear, from which there were 24 total photographs, 7 of which contained counter-protesters displaying discernible pro-Blue Lives Matter symbols.
  • 1 was an official Harris rally in Florida where Harris herself appeared, from which there were 3 total photographs, all of which contained counter-protesters displaying discernible pro-Blue Lives Matter symbols.
  • The other 15 events were official Biden rallies, White House press events, a rally for a Democratic politician, events related to the nomination of Amy Coney Barrett to the Supreme Court (including ones affiliated with the Women’s March), and photographs taken outside Trump’s October 15th Town Hall, from which there were a total of 310 photographs. I didn’t see any pro-Blue Lives Matter or adjacent symbols in any of these photographs.

The symbols described above showed up in the following notable ways:

  1. Flags and banners being carried by supporters

3. On flags containing blue, green and red lines to show support for law enforcement, federal agents like park rangers (some consider the green line to represent the military as well) and firefighters, respectively.

In some cases, symbols appeared that could have been intended to support the Blue Lives Matter movement, but we cannot know for sure. Examples include:

  1. “Law & Order” symbology

2. A Thin Blue Line-esque symbol with the blue line replaced by a blue rifle, over the words Trump 2020”, probably to symbolize support for law enforcement, the second amendment and Trump

Caveats

  • The number of available photographs with pro-Blue Lives Matter symbols on Getty Images from a specific event doesn’t tell us much about the total number of occurrences of those symbols at that event (the photographer could have not captured all instances of a symbol or could have captured the same instance of a symbol more than once).
  • This data spans only two weeks’ worth of events.
  • In 2016 the events span only 9 states (New York, Ohio, Wisconsin, Virginia, Florida, North Carolina, Pennsylvania, Nevada and Colorado), while in 2020 the events span only 14 states and DC (Arizona, Pennsylvania, Nevada, Wisconsin, Michigan, California, Florida, North Carolina, New York, Georgia, Massachusetts, Iowa, South Carolina, DC and New Jersey).
  • Some photographs contain hundreds of symbols that I combed through manually, so I may have missed symbols that were not displayed prominently enough.

Conclusion

From this limited data, we can reasonably conclude that the prominence of pro-Blue Lives Matter symbols has increased at Trump rallies between 2016 and 2020. This data alone is not enough to quantify the extent of this increase or whether this phenomenon is visible across the entire country rather than just in the specific states listed above.

On Monday, October 26th, the New York Times’ Daily podcast aired an interview with three suburban white women in Ohio who are supporting Biden in 2020. One of the interviewees, who had voted for Trump in 2016, talked about her experience learning about systemic racism in America after the police killing of George Floyd, saying she felt that the Republican Party is not doing enough to confront it. Even as Trump’s stance on law enforcement and the Black Lives Matter movement costs him swing voters like this woman, it has clearly galvanized many of his supporters. And his campaign remains steadfast in its messaging.
