Trying to continue with an earlier thread about passports and documentation...

Actually, @azas, there have been crimes committed by undocumented immigrants from Mexico. Unfortunately right now it is very easy for criminals to cross the border and commit crimes, and some of the ones who have murdered innocent Americans had committed previous crimes, been caught, and deported before.

This is not to say I believe all people who cross the border illegally are violent criminals. Far from it. However, it still makes sense to have a more secure border which provides a clear pathway to legal entry for those immigrants we believe would be beneficial to our country while barring entry to those who would be detrimental. For example, someone who could be barred from entry would be someone with a criminal history or record. Those who talk about securing the borders are not racist or anti-immigration. They simply want to know that the people coming in are people of good will, and they would like to keep the bad guys out, especially the known bad guys.
