CVA/PIE and such are 'only' paramilitary organisations are not officially involved in protection of Amarr citizens. From RP view there was no real reason for us to be involved. Maybe next time they'll call us for help since we've been fighting U'K for ages, and... maybe not.
On the other hand it's always annoying to be left out of the scarce amount of RP events that actually happen around the Eve universe. Especially when it concerns Amarr and U'K.
EDIT: And as for this thread's title, that's what usually happens during the events.
