Such a case happened the Bryan/College Station, TX area, where Texas AandM University resides (text and photos from Buzz Feed, hat tip to Sister of MIM).
On June 28, Lt. Col. Roy Tisdale, a Texas AandM alum, was killed during a training exercise at Fort Bragg by another solder who then shot himself. The Westboro Baptist Church, known for protesting soldier's funerals with anti-gay messages, posted plans to show up at Tisdale's funeral on their website.
A fellow "Aggie", Ryan Slezia, came up with a plan to create a human wall to block any protesters from getting near the funeral, and invited fellow Texas A&M students and alum to join. One participant tweeted that over 650 people showed up in maroon shirts to create a "maroon wall". It appears that the Westboro protestors never showed up.
As anyone who lives or is originally from Texas knows, you don't mess with Texas Aggies. So here's a big "Gig 'em" and "Whooop!" to all those who showed up to defend the family of Lt. Col. Tisdale from these scumbags who have the audacity to call themselves a "church."
