Has anyone ever heard of this? I was browsing wikipedia the other day and came across this article:

http://en.wikipedia.org/wiki/Fleeing_felon_rule

In Common law, the Fleeing Felon Rule permits the use of force, including deadly force, against an individual who is suspected of a felony and is in clear flight.[citation needed] Force may be used by the victim, bystanders, or police officers.
I've been unable to find an actual Federal Law that says anything about this. I'm wondering if this is legit or if it's just another BS wiki article that someone invented. It's interesting because in theory it may sanction the use of deadly force against a 'retreating' assailant.

Any ideas/laws?
