Possible......but perhaps you should check citizen arrest laws for that State. You may be surprised.
I'm aware of their laws and the fact that the two vigilantes started out with in their rights.
If it comes down to knowing the guy knew exactly who he was after prior to starting to chase him it'd mean the guy had valid options that he chose not to take advantage of.
That's what the cops are for..
It wouldn't set well with me if I were on a jury...
