The latest edition of a historical marker honoring the life of Emmett Till is bulletproof, according to the Washington Post. Till was a 14-year-old black boy who was falsely accused of grabbing and whistling at a white woman and killed by two men in Mississippi in 1955, creating a significant and painful rally point for a burgeoning civil rights movement. The new marker is at Grabbal Landing near the Tallahatchie River, where it’s believed Till’s body was found; previous markers at the spot have been stolen, vandalized, or shot full of holes.

According to the Post, the new sign, installed on Saturday, October 19, weighs 500 pounds — no small feat for would-be thieves to walk off with. It’s made of steel and has a sheet of bulletproof glass covering the front. Patrick Weems, the director of the Emmett Till Memorial Commission (ETMC), told the Post the sign will also be monitored by Internet-connected security cameras for the first time.

In an Instagram post from the studio that designed the new sign, it can be seen that the marker mentions the history of the spot both before and after Till’s case became national news. It includes details of how enslaved people cleared the area in the 19th century and information on the recent spate of theft and vandalism amid efforts to memorialize the spot. It also notes how ETMC founder Jerome Little has observed that the spot is “a beacon of racial progress and a trenchant reminder of the progress yet to be made.”

Dave Tell, a historian who wrote the sign’s inscription, told the Post that while the latest sign is a more heavily fortified reminder of both distant and recent history, it’s not expected to be invincible.

“By drawing attention to the vandalism at the place, I’m trying to say the vandalism and the bullet holes are part of Till’s story, too,” Tell said. “We don’t want to brush that story under the rug.”

“I don’t think anyone on the commission sees the bulletproof sign as a cure-all,” he said. “In some ways, it just feels like a bigger target. Personally, I would not be surprised to see it vandalized again.”

While there is hope the new sign will be more last, the ETMC will not give up on efforts even if it is vandalized again.
