No way to get true identification of any illegal.

We had an illegal alien who committed a murder under the name of Joseph Smith. Give me a break. No one in law enforcement questioned his ID. So much for ever knowing the true ID of this man.

There is no way to know the true ID of illegals using false documents if there is no criminal record in this country to check against. How do you check criminal records if a crime had been committed in Mexico with no record to share? Useless ID cards. This amounts to no more than to give a free pass to all illegals. Even criminals who have no background to check against if they have 10 different false Ids to choose from. All they would have to do is choose an ID they have no criminal record against.

Background checks is of no value in determining who is a criminal or not.

There is no way to identify any of the illegal as to who they really are and if they are criminals unless they have been finger printed and have been charged with a criminal act in this country.
