what does the constitution say about a fugitive from justice (extradition)
Article Four of the United States Constitution Clause Two requires that fugitives from justice may be extradited on the demand of executive authority of the state from which they flee. The Supreme Court has held that it is not compulsory for the fugitive to have fled after an indictment was issued, but only that the fugitive fled after having committed the crime. The Constitution provides for the extradition of fugitives who have committed "treason, felony or other crime." That phrase incorporates all acts prohibited by the laws of a state, including misdemeanors and small, or petty, offenses.
Fugitive Slave Act of 1850 In response to the weakening of the original fugitive slave act, the Fugitive Slave Law of 1850 penalized officials who did not arrest an alleged runaway slave, and made them liable to a fine of $1,000 (about $29,000 in present-day value). Law-enforcement officials everywhere were required to arrest people suspected of being a runaway slave on as little as a claimant's sworn testimony of ownership. The suspected slave could not ask for a jury trial or testify on his or her own behalf.[6] In addition, any person aiding a runaway slave by providing food or shelter was subject to six months' imprisonment and a $1,000 fine. Officers who captured a fugitive slave were entitled to a bonus or promotion for their work.
