2nd Ammendment right against tyrants in our government?

Lets say for example, a prosecutor throws the book at my 80 year old mother for J walking and prosecutes to the full extent of the law causing her to be jailed and die in jail in a week. Can this prosecutor be viewed as a tyrant under President Jefferson, Washington & first Secretary of Treasury Alexander Hamilton's statements. Basically when they said the 2nd Ammendment is also to protect us from a tyrannical government, let the government know that the people will take arms against tyrant's when all other recourse fails. Question: Is this prosecutor a tyrant?
