if immigrants are just freely able to come in and out of the us then there is no telling what they're planning so just to be safe from any types of attacks buld the wall!!

Today we found out once again that our failure to control illegal immigration and our inability to manage the current caseload of people applying for immigration benefits poses a lethal risk to the nation... terrorists can and will take advantage of the same unenforced immigration policies that have flooded this country with illegal immigrants - we now have irrefutable proof that the terrorists understand where we are vulnerable. We can be certain that there are many more terrorists who entered the country illegally or overstayed visas therefor the wall will be a great help to contest terrorists from getting in the us.
