We do have a right to protect ourselves from clearly dangerous activities and abuses of our rights. That can include filing civil lawsuits where appropriate. Yes, I do know that there is a theory of assumed risk and you cannot sue at the drop of a hat. But actually through a number of acts our government has determined that illegal aliens are a clear danger.

In 1798 Congress authorized the "Alien-Enemy Act" which still has been held by the Supreme Court as applicable law.

The Immigration Reform and Control Act of 1986 spelled out most of current immigration law, and then was modified in 1996. The US State department has issue directives identifying illegal aliens as dangerous to US citizens. Congress has not distinguished some illegal aliens as safe and some as dangerous. It lumps them all together--to equally protect us from Chinese or Iranian illegals or those from Britain or France. Although there are other distinction for those with origination from certain countries.

If a business comes to our home, or to our neighborhood, which employs unauthorized aliens is it not possible that we are placed in danger? One day that business may have a Mexican--the next day it might send a jihadist from Afghanistan--we just don't know. If we walk past a site employing illegals are we not placed in danger?

If any amnesty to illegals is granted by the US Congress then these people will have legal status and will not--all conditions being equal-- be in the dangerous category. So I would act soon. What do you all think? Even in small claims courts the limits have risen quite a lot in the last few years.
