Okay, I've reviewed the clips here and there's a few things that I've noted.
There is no clear evidence at all that they 'threatened you with a gun', except for the part where he flashes it through the window... but the gun is on safety. This means that he isn't an active threat. This leads me to believe that the time BEFORE the clip, the gun was also on safety (although there is obviously no evidence of this).
You also say to them that they can keep the money, then ask for it back, I get that you were trying to case the place.
It's quite clear that you maybe need to learn the difference between an active and inactive threat. As you were banned literally yesterday for NLR and Minge behaviour, I'm going to deny this. Use this time to read the rules on killing.
