You say 'Maybe' now:
This was discussed after you put up this appeal on forums ( a few seconds later ).
If a player wants to rob and run away (considering he had 2 infernus' in this case, one of his own and one of Raptor's) he would run "away" after he has attempted to rob you. This looked more like a showcase of popping all the 4 tires then jumping back to his and then running away. It seemed more like your aim was to pop the tires and not to kill him.
Please upload the full video without speeding up the video on his robbery part.
