If EVE was not an open world PvP game wouldn’t CCP already made ganking in hisec impossible (for example by simply disallowing red safety in hisec)?
they do not have a mandate to protect attacked players and as such will not necessarily be able to prevent eventual losses if attackers can field sufficient firepower to destroy their targets before CONCORD can intervene. CONCORD should therefore be regarded as a force of retribution, not one of protection.
