And what if you're bringing something else to the system for undermining purposes, or planning to extract something from the systemIf the Power Security ships would scan you, and open fire only if you are bringing Power commodities to the station for undermining purpose, that would make more sense to me.
A probably incomplete list of things you can use for undermining if you can get them into the system:
- limpets (in at least five different ways, in some systems)
- low value cargo
- locally mined commodities
- any commodity usable in a donation mission (roughly: any commodity the system imports)
- credits
- ship-mounted sensors
- ship-mounted weapons
- an on-foot suit
I agree that if you can get into the system carrying none of those the Power Security should leave you alone.
