Entering Illegally is a Crime!

There seems to be a very common link between immigration and the crime rates of a certain area of the world with a high level of immigrants.  What needs to be determined is how much of this behavior is due to illegal immigration and how much of it is coming from people who arrive in a certain area legally. In most cases criminal activity is more likely to be conducted by illegal immigrants because they are already breaking the law by being inside a country without making their presence noticed by the law.
