Selective prosecution obvious comparing City to County

A man in the county opens a gas main and causes an explosion in his house and no charges are filed. A man in the city, with no intent to blow himself or anyone else up, imprudently stores gunpowder is arrested, denied bail, has legal weapons confiscated, has legal cash confiscated and pleas to charges which deny him many rights for 3 years. One of these men had a mens rea; the other does not.
