Cold case units/departments.
A cold case is any criminal investigation by a law enforcement agency that has not been solved for (generally) at least one year and, as a result, has been closed from further regular investigations.
Cold case units reexamine these closed cases and try to solve them.
I am going to give you my honest opinion. I believe our country is still fighting against discrimination against today's immigrants because of the president we have. Immigration should not be restricted because without some of the immigrants we have here in America, we'd be limited in what we know and have achieved. Say for example, if Christopher Columbus never immigrated from England, he wouldn't have found the New Land of America (not to say that he founded this land in the first place but that's just a general example). Ultimately, if you were Hispanic, African, Asian, or even from Canada, you should still have access to a freer country such as America, where rules are lessened and given less strictness. That's my opinion, what's yours?
