how could bo and luke dukes use dynamite if they couldn't use guns?

On the dukes of hazzard how is it no and luke couldn't use fire arms but could use explosives? Wouldn't it still violate there probation?

Dynamite is not a firearm and was often used as a tool to blow stumps and other purposes on the farm.  I think it was after the Oklahoma City bombing that tighter regulations were placed on TNT.

What does this have to do with real life law and ethics?
