Like the one from the Chattanooga, TN shooting?
The most common indication of photoshopping is repeated patterns. The bird and the silhouette are exactly the same. I’d rather see a “no guns allowed” sign that is riddled with bullet holes.
You would have liked Westford, MA, Route 110, entering from the east. For some reason (guess) back when Mike the Good was governor, as you most towns in the Commonwealth there was a sign stating that town's gun policies, basically, no hunting without the owner's permission, discharge of a firearm with 500 feet of a dwelling, etc. This one had about three inch hole blasted through it. Most of the signs in just about all rural towns were pretty badly shot up. I think the towns gave up and stopped posting them.
