If so what is the need for a stronger refugee laws and control?
The primary problem is that we don't have good sources for the data. From your link:
- The screening looks for indicators, like:
- Information that the individual is a security risk
- Connections to known bad actors
- Outstanding warrants/immigration or criminal violations
But where do we get that data? It's not like the country they're fleeing would give us that kind of information even if it had it. And it's not like the "bad actors" will tell us.
Basically we check to see if we've previously encountered the individual. If we haven't, that person generally passes those checks. The interviews are more likely to catch someone who has been radicalized without previous contact with us. But they aren't perfect.
A side issue is the problem of radicalization in the United States. This more often happens with the children of immigrants than with the immigrants themselves. The children might be born in the United States. No screening process will ever catch that.
