In Nigeria, gun ownership is prohibited. So, only the bad guys have them. From Sun News Online:

Will the Nigerian Government stand idly and watch as armed hoodlums decimate Ni­gerians in their thousands before it can do the needful to legalize individual firearms own­ership under certain regulations? My take is that the Nigerian Government must liberal­ize firearms ownership in Nigeria as one way of safeguarding right to life since the armed forces and police have proved seriously chal­lenged and unable to be everywhere to pro­tect the lives of Nigerians and the constitu­tion makes it imperative that the security and welfare of every citizen is the primary duty of government. A stitch in time saves nine.

Read the whole thing. Groups like Boko Haram operate without opposition, killing and kidnapping at will because their victims are unarmed.
