"SECURE THE FRIGGIN BORDER!"
And like I said in my post the Boston marathon bombers did not come here illegally
Incidentally the 9/11 2001 terrorist also came legally here
"Secure the border" means different things to different people. In one way, it can be taken as "don't let people in, illegally," and in another way, it can be taken as "don't let terrorists in, not even legally."
I wouldn't call a border secure, if it allows terrorists to immigrate / naturalize legally.
