english: With those three systems, you have what is always necessary -- a level of redundancy that says, if one system fails, you'll still have a way to make sure that you're being controlled.
non_english: Sa ova tri sistema imate ono što je stalno neophodno -- nivo preopširnosti koji kaže, da ako jedan sistem otkaže, i dalje imate način da budete sigurni da će vas kontrolisati.
