PETA made their bones protesting the use of animals in an experimental setting. Somehow, they missed this.

Environmental Protection Agency (EPA) researchers exposed mice to gun smoke to see if using firearms could cause “acute lung injury” or “other longer-term disease,” in a study funded by multiple federal agencies.

The Daily Caller,

After exposing the mice to smoke pollutants, they tracked their breathing for an hour and then euthanized them. Once researchers euthanized the mice, they collected blood from their hearts and fluid from their lungs to be analyzed.

The Daily Caller,

Silence. I guess not all animal testing and is bad.

I’m having a little trouble figuring out how the testing protocol reflects real world situations.
