I was just think about what Robin Hood really was - he rebelled against high taxes!!
I don't think it was "taxes". The "taxes" were set by the king, who was off fighting a war in the Middle East and using that tax money for finance the war effort.
The sheriff just "seized" property. The property seized was mostly chickens and farm animals. Occasionally it was crops, silverware, jewelry, coins, etc. It would be like today if a cop just took your car or TV as "evidence" or some other lame excuse and then made personal use of it.
