-Does the Torah Allow Its Citizens to Take the Law Into Their Own Hands?

“Does the Torah Allow Its Citizens to Take the Law Into Their Own Hands?”
(updated and revised from Matot-Masei 5762-2002) 

In parashat Masei, we encounter the fascinating and perplexing law known as Eir Miklat, the City of Refuge. It is to the City of Refuge that an accidental killer must run in order to escape the vengeance of the next of kin, who has the right to kill the perpetrator if he catches him before he enters the city. Does Judaism allow its citizens to take the law into their own hands?
