furthermore, the warship must not be grouped with a pirate that is pirating. ( see the teamed example at the start ) - both ships must not be associated with each other or they become part of one and the same pirating event.
Not true, while specifically in group all members of the group in a gunboat or less are part of the piracy event, but since a cruiser cannot pirate it is automatically exempt from this rule, since it cannot be a part of the piracy event. However, there is no reason why anyone can't be grouped with them. Otherwise you'll just get a pirate cruiser hanging around the group PM'ing each other privately and not being grouped, to get around this frankly silly idea.
that is why i made my first example with the grouped pirates hanging out at different spots, but grouped. - if a pirate grouped with another pirate in the same system working together means that they form a single unit, - than this applies to a warship, too.
so if a pirate can make a demand, and let his buddy - back at the lane - do the killing job ( just in case ) ... - meaning the second pirate dos not need to make another demand but can actually open fire right away; - than this means that a destroyer grouped with a pirate in the same system, forming a single unit is to be considered part of the piracy, too. ( same logic for both incidents )
i do belive that a warship fending off lawfuls that would become part of the piracy event... would become part of the piracy event itself, henceforth is violating the rules, cause it must not become part of piracy.
