In a recent news article on USA Today it is revealed, that the US government plans to fingerprint U.S. residents with green cards, parolees and Canadians. Until recently Canadians and Mexicans were the only foreign nationalities that did not have to go through this procedure.
Remarkable is this sentence "The purpose of the program is to screen out criminals and make sure that travel documents aren't forged." (cited)
Or translated, this means: Canadians and green card holders are suspicious and more likely to be crimanals then Mexican citizens and U.S. citizens. Hm. Lets continue to read:
"Canadians — including nurses, agricultural workers, students and religious workers — will be required to enroll" (cited)
So Nurses, Farmers, Students and Priests are more likely to commit crimes then people with other professions?
Doing a couple of quick google searches, I came up with this site. From this website it is obvious that the Homicide rate in Canada is quite a bit lower than that in the USA or in Mexico. In fact of the worst places for Homicide, Mexico ranks number 6 after Columbia, South Africa, Jamaica and Venezuela.
Disclaimer: I have come to know the United States, Canada AND Mexico as wonderful places with friendly people. I have never felt unsafe in any of the three countries! I am merely trying to point out that some of the classifications are not really transparent to most of us.
