Why is illegal immigration so confusing?

Can someone please explain to me what all the confusion is over solving the problem of illegal immigration? The problem has been around for year. Why is this problem such a hard one to solve?

Here are some articles in recent news. Perhaps you can help me figure out why illegal immigration is a problem and how to solve it. At one time I thought I had it all figured out. Now I am just confused by all the differing opinions and ideas from extremists on all sides. I am not sure which of my leaders to trust to do what is right or if they are even trust worthy. What do we do, people?
