More Thoughts

1. My statements are not political.  I am not suggesting the law should be repealed. I propose a simple non-partisan modification.
2. It is important to do the right thing even if based on where you live and/or your ancestry, this law is unlikely to impact you.
3. I understand the federal government hasn't done enough to stop illegal immigration and I can validate Arizona's desire to send a strong message that if the federal government doesn't do the job, it will. However, tiny modifications to the Arizona law will ensure people from all races are treated equally and fairly.
4. I can think of countless examples I've directly experienced or witnessed at work, church, in the neighborhood, or with friends, where unconscious stereotyping has occurred despite training manuals.  I can share with you specifics if interested.  The point is it will be nearly impossible not to have any unconscious bias in considering Mexican appearance as a factor in determining reasonable suspicion. And unconscious bias is just as harmful as intended bias.
5. Regarding the practicality of asking immigration status of everyone legally stopped, arrested, or detained. There is precedent.  Everyone is asked at border crossings or when flying in from overseas.  Everyone is asked, or at least should be asked, before starting a job.  The Prabhu Solution will make it easier for law enforcement to address illegal immigration because they will get to ask everybody, who is arrested or detained, for proof of legal residency;  they won't have to consider reasonable suspicion or worry that they may be using race as a factor.
6. It is not fair to only penalize those, most of whom are U.S. citizens and/or legal residents, who happen to look "illegal".  Everyone in Arizona needs to adhere to the law and carry proof of legal residency.
7. Opinion polls suggest many think it's okay to use race, ancestry, ability to speak English, and cultural customs (e.g. looking or not looking at someone in the eye) as factors in determining reasonable suspicion since it will help enforce the law.  i.e. the end justifies the means. This view saddens me especially when with trivial modifications it can be made fair and make it easier for peace officers to enforce the law. Regardless of your faith, I leave you to consider Matthew chapter 7, verse 12: "Do to others whatever you would have them do to you.  This is the law."
