"It should, or may be, illegal to summon a person as is faerie fog. Justices shouldn't be doing it, unless the person is already wanted."
Its not illegal to summon people. The faerie fog is a fineable offence. (which is gay as well in my opinion) - but there's nothing illegal about summoning, or gating to people in town. I've seen a few people get wanted for summoning the Justice in town while he's chasing, though nothing really wrong with that.
Look, its really simple. Just read "HELP LAW", those are the reasons you can be flagged and fined. Autoassist is not at all tricky to understand, this is how it goes.
person 1's group = person 1
person 2's group = person 2, joe and bob
If person 1 attacks person 2, joe and bob autoassist, this is legal, its group defence.
If person 2 attacks person 1, joe and bob autoassist, they broke law, its a gangbang.
It is EASY TO TELL which of these scenarios we are faced with by observing the yell actors.
Now applying this situation to what came up in the log, this is a case of person 1 (special guard) attacking person 2 (the wanted guy). therefore the flag wasnt fair under the autoassist rule.
HOWEVER. Help law 3 MAKES this illegal, under the obstruction of Justice rule. Its a straightforward case, that could have easily been clarified by reading "HELP LAW". Tough luck Vissith, but you deserved what you got. In short, you can autoassist as defence of your group, but not when the attacking party is a special guard.
