Precisely. And if I were to get caught, I'd stab someone in the eyeballs with an icicle and cut out their tongues and hands with a breadknife which would then be put in a furnace, then let them die. The weapon melts away, and in between death and dying, they had no form of witness/evidence. Oh, and to cover up my footprints, I'd steal the victim's shoes, and wear them at the crime. They would then realise that any evidence they do find is probably a lie and they wouldn't be able to tell truth from false.
