Tell it to the puppets. Imagine the scene - you go in a dark street, here three people come out and ask the citizen, You agree to give us your iPhone and wallet? " - he is such "no" - they give him "then all the good" and they go by.
No, they will rob him. Then they will be planted. And no one "he himself went to a dark street with an iPhone" will not save them. On the contrary, an attempt to justify your crime, rather than pure repentance in what you have done and awareness of your wrongdoing, can increase the potential term.
