That was what they said. In Nigeria, your voice is actually your power. For instance, in Lagos, if your voice is rugged and threatening, you will be more or less like Conan the Barbarian. This is applicable to many streetwise situations but not applicable in the presence of Nigerian soldiers.
How can your voice be your power in front of a soldier who has slept the thick forest of Sambisa or has travelled to many African countries for peacekeeping? If your voice should in anyway deceive you to talk about your right in the presence of any Nigerian soldiers, then you will see the reason why Peter in the Bible denied Jesus 3 consecutive times.
A beating of different calibre will be exacted on you and then you shall believe a say by the elders which state that "If snake refused to act like itself, children will use it to support their trouser as belt".
