BOSTON (CBS) — What happens to the firearms that Boston police take off the streets?

It turns out that they end up as manhole or sewer covers, police shared over the weekend in a blog post titled “Ever Wonder Where Guns Go To Die?”

Police said the guns are taken to an Everett steel plant, “where the guns are crushed, melted down, recycled and repurposed.”

More than 200 weapons were recently taken to the Schnitzer Steel Plant, and police posted pictures from the trip.

“It feels good knowing that the weapons destroyed here today won’t get a second chance to hurt or harm anybody else in the future,” police quoted one officer as saying.
