Last year, a squadron with around 18 (massive, I know) active members was holding off an offensive from one of the top 10 membership squadrons - they called for help from said 'lawful' group as the squadron they were having such problems in squashing had a very well-known ganker as an officer. Said group arrived, did not find the 'criminal scum' promised so spent happy hours blowing up innocent traders and explorers...
Even I had a wing of 4 'lawfuls' interdict my stock eagle with no weapons, shields or armour - and no fines or bounties either - and spend a happy few minutes chasing me around before succeding in KWS me, then to hit me and blow up my obvious gank ship... While they were 'busy' facing my threat, 4 others from the squadron I was in launched and took care of the second wing that were rushing to the aid of the first...
Yeah, proper lawful... I was there, I even have the video, as, naturally, I'd started recording to show the ship was clean and totally harmless before launching from the pad.
