Questions regarding indie coalition ID

[Mímir]

The ID says it's allowed to shoot Navy and Police players all over, which is great.

But how about Corsairs and Outcasts? They are on the list of SCRA traditional enemies, can I really only shoot them when/if they are carrying artifacts/cardamine?

"Can attack any ship to protect an alllied ship" is the clause indie Coalition ID'd players would be using on Gamma raids fighting alongside Hessians and such things, then?

Can the same clause be used join IMG against Outcasts in Tau-23?
