There are threats in the world but picking the needle out of the haystack is very difficult and my biggest concern is how data is interpreted. If you were attempting to enter the US, migrating from Turkey and I determined that 3 people within your social graph, one direct connection 2 secondary are known terrorist does that mean you are a terrorist based on no other information? It's really hard without direct evidence and we're playing with peoples lives. The vast majority of people are no threat and will be productive members of society.

I am afraid the guilt until proven innocent mindset in regards to immigrants is increasing in parts of the US. I wish everyone would settle down and relax for a minute but it seems like thing will only continue to increase as we begin to enter a new election year and then start what will be a very heated Presidential campaign.
