All angels are considered criminals according to CONCORD and Caldari State legislation. If I will shoot an angel without a criminal tag and will be arrested, it’s enough for me to present evidences to the tribunal that the target I destroyed belonged to Angel Cartel to be released.
The only reason when I can not shoot an Angel Cartel employee or asset, is when they surrender. I will have to detain them or capture intact in that case, which I really don’t like doing.
According to regulations, an encounter of a confirmed member of a pirate organization (e.g. Angel Cartel) wearing a confirmed weapon, or flying a combat ship is a reason to shoot on contact without asking to surrender.
On encounter of unarmed pirate, I, unfortunately, will have to detain them, and I am allowed to shoot only if they will resist.
And I am obliged to accept surrender of armed Angel provided they put down their weapons before or during the fight.
Luckily, majority of Angels are already tagged by CONCORD for elimination for every pilot who will see them.
