Kind of a bad defense for a couple reasons Spray.
1st, he wasn't "just coming out of CI base", Human even made sure to go through the tree line so you couldn't sit there and camp him on the way out.
2nd, going off what I just said in the last part, why are you on Pathfinder just to puppy guard CI base? CI nor GOC do that, yet I see a lot of people on Pathfinder doing that recently, you guys should be warned just for that alone.
3rd, you have to be blind to see he didn't even react to you shooting him. So how did it not click to check who you shoot before killing him? Even if you knew it was CI you're supposed to actually AOS them and RP that out before murdering a possible Foundation member.
4th, even if it was a genuine accident, though it definitely doesn't look it, RND are non-combatants, they have been for some time too, so topping the camping, you also apparently ignored an incredibly important rule.
5th and lastly, joking about it after you can see the death card and their job is extremely immature from an Admin, though there isn't proof of that here, so I'll give the benefit of the doubt, if that did happen it's just downright upsetting you didn't even apologize or at the least didn't do it seriously.
In the end +support, but the end decision is up to higher staff.
