Blue stripes have been quickly appearing on street curbs around the United States after Texas man posted a message on his Facebook urging friends to paint thin blue lines as a show of support for law enforcement.

"This initiative has grown into what I had hoped, the silent majority coming together to show our police they are not alone, are greatly appreciated and fully supported in our communities," Anthony Welichko of San Antonio wrote on September 17, 2015, a week after he initially posted his idea.

"Grab a can of paint and go for it," Welichko said.

He calls it the "Safe Harbor Initiative."

"Too much attention (in my opinion) is being given to those who wish our first responders harm and not enough to the majority that appreciate the risks these fine men and women take every day to protect us."

"To all law enforcement who see this line, know that the residents of this home appreciate your service and dedication to keeping the peace. Know that when you enter the neighborhood and see these lines that you are not alone or without 'back-up.' We do not need the media to make our voices of support for our police and emergency services heard ( though it would be nice). Lastly, if you are in my neighborhood and mean to harm a member of law enforcement, know that decision may be hazardous to you health as someone has that officers back!"

Welichko shared artistic advice to those who live where utility companies use blue stripes to mark water lines. "If this is the case in your area then add a little something else to it. Or, in the case of those without a curb, use a large rock or a nice block from the hardware store."
