for the performance of their duty,”42 which means that their use should follow the principles of necessity and proportionality. As mentioned above, a law enforcement officer can only kill if it is required to save life, which would make the use of lethal force proportional; and only if there are no other means available to prevent the threat to life, which means lethal force is necessary.43 The principle of proportionality assesses the amount of force that is permissible or reasonable to use for the objective to be achieved. For example, the authorization by the Israeli authorities for the Israeli forces to use live ammunition against youth throwing stones is not proportional, as they are not posing a threat to life and therefore lethal force is not justified.44 The necessity principle, on the other hand, establishes an obligation to use the least amount of force necessary to stop that threat, and only when other kinds of force are unavailable or have proven ineffective is the use of lethal force allowed. This means that lethal force must always be a measure that is used as a last resort and absolutely necessary to protect life. Further, the Basic Principles limit the use of lethal force to three cases; selfdefense or the defense of others under imminent threat of death or serious injury, prevention of perpetration of a crime involving grave threat to life, and arrest of someone presenting a serious danger and resisting the authority, or to prevent their escape.45 Israeli Policies and Practices October 2015 and after At the beginning of October 2015, Palestinian frustrations grew over ongoing violations of their fundamental rights. This frustration was met with a sharp increase in the illegal use of force and collective punishment by Israel,46 which claimed to be responding to alleged attacks and protests by Palestinians. These actions lead to an atmosphere of insecurity and instability throughout Mandate Palestine.
