If people of any country suffering from poverty or they are jobless or homeless, it doesn't means they'll scam us. There are lots of counties where people have similar situation. And maybe they also do scamming. So why only mentioned Nigeria? I can't deny i saw and heard that Nigerian people were responsible for scamming but scammers aslo live in your's country too as well as mine. So it isn't logical to blame only Nigerian
True, nothing justifies robbing others of their hard-earned money just because you are being robbed by your governing the name of tax and corruption and also scammers originates in all the nations but Nigeria had been made popular I don't think it's right to stigmatize issues like this. We need to work on putting these scammers behind the bar as only a severe punishment will discourage others from scamming and i remember how some call centres in India was raised for running a scam projects scamming elderly people in USA.
