There is no way to let the good people in and keep the bad one out. Why do you thing Islam recruits first in prisons ? It is an evil cult bent on destroying the world.
A Muslim man can have four wives making as many children as possible. While earths population is sucking the life out of our planet, they make millions of babies, raise them to be martyrs and suicide bombers, hating virtually the entire human race.
The world should confine them to their home lands.

@David42 i agree - no way to be sure who is coming into the country, but with proper vetting one might at least try to reduce the numbers of radicals entering. that requires the will (and $$$) to do so. the problem is the 100,000 or so radical muslims (cair, muslm brotherhood, etc) already in the u.s. and canada who are diligently working to overthrow the nation.

as to recruiting? that didn't begin in the prisons but rather in the universities and colleges - in the early '60s according to their own documents. they chose universities for a number of reasons: the malleable, young minds who attended were "anti-establishment", unhappy with the status-quo, and seen to be more open to inclusion and acceptance of foreign ideas even if the utopian idea was completely counter to the reality.

muammar gadaffi said in the 1975 “We have 50 million Muslims in Europe. There are signs that Allah will grant Islam victory in Europe— without swords, without guns, without conquest—will turn it into a Muslim continent within decades”

pew research data seems to show that gadaffi over-stated the number, but the comment is accurate. muslim families in europe have an average of 7 children per family. european families have an average of less than 1.3 children per family. a nation's population is not sustainable at those rates and, yes, gadaffi was quite accurate in the statement that europe will be a muslim continent - fact, not speculation!

as for the u.s.? look at congress for how far they have come to proving gadaffi right, and right here.

it's time to wake up.
