My shiftydar says that something shifty was going on that day.
I was there with the Global Electronics raiding crew.
If I remember right, we started the capture and terminated the Vtec strays nearby, then a squad came but we mostly pwned them, yet Lawyers mysteriously didn't fight a single vtec there (I never heard any shots), even through there was at least one Vtec in the building we were getting cover.
We were attacked by BBs early on, but I and a few brave patriots repelled their attack and they apparently decided to abort mission because they left just as Lawyers showed up.
There's also the fact we saw zero ZC between Vtecs and Lawyers after a certain period. Could be chalked to night, but Vtecs were almost without territory yet they were coming after us instead of nabbing easy lawyer territory near their turf. They were either spoiling for a fight or something suspicious is going on.
I don't think a faction-wide alliance is going on, but there's def a squad or platoon-sized non-agression pact there.
