Everyone has an "unknown" background to some extent. That's a hell of a thing, have you videotaped your entire existence? Yes it's true we can check where you went to school who your relatives are etc. but how do we know u haven't done bad stuff at some point or maybe you do it secretly even now?
Fact is, if you are automatically paranoid of "unknown" you can harm people. While paranoia might reduce your own risk overall more people are hurt by paranoia than are helped.
If the narrative that illegal immigrants increase crime how come the number, and especially the rate, of murder and violent crime has drastically reduced over the last 25 years? In fact we are at historic minimums in terms of crime. In fact, statistically, there is a strong case for the fact that illegals have caused a violent crime reduction.
Refugees, nearly always, can't prove their background. If they are fleeing persecution do you think they had time to get all their background checks and certifications done? I will bet money that a majority of people who hate illegals will not hesitate to illegally immigrate somewhere if they were facing a dire situation at home. Like many people claim they won't steal under any circumstance. What if your and driving with family and get in an serious accident on a desolate road and your family is hurt in it .. there is no cell phone service but there is a locked holiday cabin with a phone and first aid supplies. I bet cash money most people will break into the locked holiday cabin to steal the first aid kit and make a phone call to get help.
Yeah so all the hate on illegal while maybe 1 out of 10 might be bad don't forget about the other 9. We have had a huge influx of illegal immigrants yet there has been a REDUCTION in violent crime.
