Like I said previously, I saw nasa lingering for an awfully long time around tidals in positions that I typically see people raid/flank from. After dealing with our own KOS at southgate for cloud, we heard a shootout at tidals involving a lot of rifles, the guns they had. We decided to counter raid but investigated beforehand by having me go up to PLN to look and others go to the other entrance to look, giving us a perspective of both sides. All of this information + no "cop weapons" being heard gave us the idea that there were no cops on scene (which there weren't and there weren't any responding either). I saw multiple armed people running around the top floor which led me to believe that there was a raid occuring up there specifically in tidal 201. I then noticed someone who I thought to be in zipties (their handcuffs were just off screen) running out of where the door would be and around the window with someone pointing a gun in their general area, further solidifying my view. From there Inchs entered through the back door and the KOS began before we attempted to finish the "raid" in tidal 201.
