Text Message Trouble

Men of the Nigerian Police Force arrest Akpos and they were checking his phone.
At that moment of checking his phone, a text message comes in.

It says, “Please, if you are coming, buy one Ak-47 with 6 bullets so we can be prepared for tonight’s operation.”
How would Akpos explain to the police that his friend meant Vodka (Ak-47) and Energy drink (Bullet)? To make matter worse, his friend’s name is Robert but he saved it as “ROB-1″ on his phone!
What should Akpos do?
