IIRC, this came up many years ago. A lot of police departments were required to go to green silhouette targets. The reasoning was that police officers were being trained to shoot whatever was a black humanoid target, as opposed to the outline of a humanoid target with a white or flesh colored face.
I normally use 6" shoot-n-see targets stuck to whatever background I hapen to have Many times a black silhouette sometimes green.
Just great! Next we will have black silhouette target hoarding on the horizon !
I saw you commented in the article.
Don't tell anyone.
The only reason I have a FB page is so I can rant occasionally.
