I live in VT and know a few State Troopers and seen this emblem many times and never noticed the pig on the cows body. This has been on the cars for 4 years now. Apparently no one else noticed it either.
On the other hand no one had noticed this over the last 4 years, so why didn't they replace it when it was noticed and most of us would have never been aware of it.
The inmate that designed this must have been having a good laugh over the years. ( Maybe not now.)
I think it was a funny prank, no one was hurt, everyone should have had a little chuckle out of this and if you can't see a little humor in it you need to get a life.
Have a Great Day.
Smiling is contagious.
