If we must say there was any decision mistake from the team, it was greatly underestimating Perez's defensive ability; he should have been given strong and risky team orders earlier to make Vettel overtake at all costs.
The reason Marco and Horner didn't dare to issue such strong orders is because of a guilty conscience!
As the old saying goes, what goes around comes around. You gained the lead after Vettel gently touched Chen Xiangbei at the start; can't Perez from the HRT Team touch back?
Don't forget, the HRT Team leader is Briatore; if you want to play dirty with him, use tough moves, Marco is just a little brother!
The stronger and more aggressive Vettel's overtaking moves are, the more reasonable a collision accident involving Perez becomes, even if in the end it gets appealed to the FIA Assembly Committee, there is a high probability they will consider it an accident.
