OK Let Me give a little explanation:
So the first part: I was shaking the camera and It didn't give me any warning as you can see, I did that when I was noob and I was robbing stores for the first time and I failed because of that, well this didn't happen on the video.
Second part: I was aiming right at him, and it still failed, never happened to me before, just today, I'm gonna test it again and post the second video in the replies if it bugs again.
