Sounds like a right bunch of wrong ‘uns.
Lured, tortured,killed a man and then set about a vehicle jacking spree.
A warrant was out, several surrendered to police, others chose their own path and in firing on police, they showed their complete disregard for their own and others lives, and justice was appropriately administered.
The leader appears a charismatic and persuasive individual, judging by the numbers of people involved, good news that he is gone.
The survivors should all get suitably long jail terms.
