content: 1: shoots a kid 2: kid was not an active threat and was not armed. 3: shot was fired without checking the path the bullet would take, so unwanted targets could be hit. 4: the safety was not engaged. 5: this finger was kept on the trigger. 6: the gun was not made safe after the shot 7: attempted to fire the gun inside without ammo being loaded. 8: fired shots into the air not taking into account the path it would take so it could have hit people on other floors or bounced and hit other people on the same floor. 9: he places his hand near the operational end of the device (GLaDOS even warns about this) that's what I could see but there is prob more that someone who uses guns could spot.
