I'm far more concerned about the lack of screening for tuberculosis and other communicable diseases
Terrorists can only bump off a few hundred or even a few thousand of us, maybe a city full with the right weapons.
An anti-biotic resistant strain of TB brought in by just one immigrant from anywhere, perhaps unknown to themselves, can wipe out many millions of us.
We need to return to screening of ALL people who enter our country as well, as returning citizens who have visited countries known to have problems, for diseases.
Forget the knives, guns and bombs, they are nothing compared to an epidemic.
I’ll bet that it is already here. Some of the illegals I used to have to deal with were nasty and sickly beyond words.
