I agree with this, its poor form to accuse all the policemen involved in this incidents as cowards, some of them might have ran away, to save themselves when this shooting started, because lets be honest, with their skill level and artillery provided to them, they were never going to be a match for the terrorists, who were armed with AK-47's, rocket-launchers and grenades.
The thing is they should never have been there in the first place, special ops commandos should have been there as security to the team, but on the contrary just to have local police as the security for the both the teams and officials, and that too when the situation in Pakistan is as bad as it is, just shows how serious PCB are about player security and their safety.
IMO, people like Murali and Broad too should think twice before criticising the police officers here, I know they would be badly shaken up after this incident, but they shouldn't forget, that its because of the bravery of the local policemen, that all of them are still alive, the blame solely lies with the PCB, had they had better security plans and people at work, then maybe a situation like this could have been avoided all together.
