There are those that feel ILLEGAL immigrants should be allowed to stay here as long as they don't break any laws (although they broke the law by entering illegally).  If that's the case they should just allow all immigrants trying to enter legally.  In fact let them all in and stay here as long as they don't break any laws and arrest and deport those that do (unless they live in a santuary city).  I guess these people feel this is more important than our safety.
