We agree that its a forgery.
We agree the outside of the stamp would be worn more.
The botom edge of 08 will be crushed down when compared to the top edge.
When stamped as 2008, it will still work.
When stamped is flipped as 80, it will be crushed just enough not to print because the high side will now be on the outer edge. The inner edge of 80 will be to low to contact the paper.
This is just more evidence to back Arpiao.
Sorry, your explanation just doesn't make sense.
I'm done. Believe as you will.
