Thin Purple Line- The Community of Public Security

The “Thin Line” movement has been growing exponentially over the past decade. It has become a symbolic meaning of those in a profession that helps the community in some way. With the growing trends on social media with hashtags and viral posts, there is a famous phrase, “Thin Blue Line” or “Thin Red Line.” Depending on the line’s color, it will depend on the professional field that the movement is referring to.

The history of the “Thin Line” is a globally recognized and based on colors;

-Thin “Blue” Line: Represents the Policing Community

-Thin “Red” Line: Represents the Firefighting Community

-Thin “White” Line: Represents the Emergency Medical Services

-Thin “Green” Line: Represents Federal Agents

-Thin “Gold” Line: Represents Communications Operators

-Thin “Silver” Line: Represents Corrections Officers

The Thin Line movement is a way for workers in these fields to feel a sense of community and support in their professions. It is not always easy to continually be in the public’s eye, especially when it requires life-changing split decisions. Being a 1st responder is not still a precise and cut job description; many of these people wear many hats. So we must build a sense of community and comradery to support them be the best workers that they can.

The thin line movement has built an excellent community for these public responders. But what we have been missing is a ‘thin line’ for the public and private security sector. We have seen an increase in the public and private security sectors over the past decade, and increasingly growing numbers due to recent current events that are taking place in 2020.

While security professionals outnumber Police by an astonishing number, Police are approx, 800,000 in the profession with over 1 million security guards employed in the United States today. The time has come to create a thin line movement for our security personnel who serve out public.

Over the past years, there has been talking to incorporate the security sector into the “thin line” community. But what color would be indoctrinated into the movement? There were a few factors that went into the decision behind the color of choice:

-The color purple was chosen based on mixing the two colors of red (Fire Community) and blue (Law Enforcement Community), and also white (Color for EMS.) The color combination provides the color blue’s calmness and stability mixed with the energy and fierceness of red.

– Purple provides enough distinction from the other public safety colors, ensuring no confusion of the different colors.

There has been talk for quite a few years regarding making the Security Sector apart of the Thin Line Community. On June 22, 2020, the ASIS Global Board of Directors unanimously approved and supported the “Thin Purple Line” initiative to welcome the Private and Public Security Sector into the 1st responder “Thin Line” community.
