Now for an example, I am a US citizen, I try to get in to Canada, they run my name through the computer system that they have access to US's computer systems, they ask if i have any criminal record, yea, I have a dui, they run my name find the dui, other records pop up from 1996, Paraphernalia and Grand theft auto, which I was never convicted of, but the records still show the reports. I get denied. But the murderer is able to get in because the US or Canadian computer systems don't have access to his country's computer systems because "they might be a poor country and or don't keep record". This is all as an example.
