how is javert discriminated against after being released from prison?

Javet is actually the nasty police inspector. I'm thinking you mean Jean Valjean who was just released from prison after a 15 year sentence for stealing bread. Jean Valjean is discriminated against for being an ex-convict.When he gets to town, is first stop is at the mayor’s office.The law requires him to show a yellow passport indicating that he is an ex-convict. Tired and hungry, the town’s innkeepers refuse to serve him. Jean Valjean tries the town prison, the houses of local villagers, and even a dog kennel but nobody will give him a break.
