Protocol V on Explosive Remnants of War requires the clearance of UXO (unexploded ordnance), such as unexploded bomblets from cluster bombs and abandoned explosive weapons . At the cessation of active hostilities, Protocol V establishes a responsibility on parties that have used explosive weapons to assist with the clearance of unexploded ordnance that this use has created. Parties are also required, subject to certain qualifications, to provide information on their use of explosive weapons. Each party is responsible for the territory in their control after a conflict. The protocol doesn't apply to mines and other weapons covered by protocol II.   The protocol came about as a result of a growing awareness during the 1990s that the protection against unexploded ordnance was insufficient. The protocol was adopted in 2003 and entered into force in 2006. 
The gospels make it clear that Pilate didn't want to give a death sentence, and repeatedly tried to find ways to avoid it. For example, when he was reminded that it was customary to free a prisoner during the festival, he tried to use this as an excuse to release Jesus. But an unruly crowd in the courtyard shouted for the freedom of a prisoner named Barabbas instead. Some scholars think that the Jewish leaders "packed" this crowd with their servants and henchmen, and thus were able to control it. In any case, Pilate became fearful that the crowd would get out of control, and so he released Barabbas instead of Jesus.
Of course, the Muggle population was oblivious to who were the real culprits and why they had acted. While some Muggles, like Taylor, thought that the attack could not have been the work of any human foe (" I know that these were devils, punishing us for our decadent Western lifestyle "), others, like Lucy Evans , were more earth-bound and blamed foreigners. While no political group claimed responsibility for the attack, Spanish Liberation Group ETA and Islamic Fundamentalist Cell Al-Hiraza were implicated.  Mayor David Yates spoke to the population, urging them to be calm,  and pledged to uncover the reason for the attack, find those responsible, and prevent any possible repeat.
