But the thing is, if policemen can ask anyone for their immigration paper, what if that person happens not to have them on hand? Of if he isn't even an immigrant, he is just somebody born in the U.S.. Does that person has to carry around his paper at all time just not to get arrested?

I found it interesting that Obama's first response is that this shouldn't be a state issue but a federal one.  Just another attempt of taking away state's rights showing how little he really knows of the constitution and the desire of our founding fathers. 

To me this has got to be the longest four year run of any President.  Is it over yet? 

Policemen cannot.  They can only ask for ID (one ID, not an ever lasting string of IDs).  If the ID is not on hand, then the law provides for alternate ways to verify their residency status - with one exception. When it would hinder a criminal investigation (or the stopping of a crime).

What you are hearing is the false rhetoric of the race baiters.  It is the same tactic they used to try to destroy the voter ID law.  The strength of the law is in the truth, and unfortunately for race baiters, lies are not admissible in court (legally - it is called perjury), and when you have the truth in black and white, no one is stupid enough to try to lie in court about it.

So.... ..... ..... what is the point of the federal government writing a new law, if it's the state who's going to be enforcing it anyway? (the fed intervention KFC is so pissed about)

It is more of an administrative law and enforcement policy that the Feds have to write.  Yes, illegal immigrants already break the law (that is why they are called illegal).  But the feds are not doing anything about them (think of it as one of those old laws on the books that is never enforced any longer - like sodomy).  Since the Feds are not doing anything to enforce the law, the states (Arizona in this case) are writing procedures for enforcing the law.

The Fed intervention that KFC is upset about deals with the fact that the race hucksters at the feds are trying to interfere with the enforcement of their own law. (demigoging it). 

In other words, your government tells you to wear a seat belt.  Then when you do, they claim you are an elitist because you think your life is worth more than the idiots that do not use a seat belt.

American Politics.  You have to love it.

I'm a little mixed on this one.  I am for it because, AZ has the right to enforce laws within it's borders.  Yes, there are federal responsibilties here, but the state also has borders and jurisidiction to enforce the law within them.

The state also has the responsibility to enforce trespassing laws.  As it has been, land owners along the border have been prevented from doing anything about all the illegals trespassing, squatting and otherwise fouling up their property.   How would any defender of illegal aliens feel if people were allowed to camp in their yards.. and they were told they couldn't do anything about it?

On the other hand, I don't dismiss the accusations of "papers please" from the left.  If police officers have to establish legitimate "probably cause" to confront people, demanding their proof of citizenship, then it's not much different than police asking for proof of insurance, registration and drivers' licence during a traffic stop.

However, the line between that and stopping people just to challenge their citizenship is no small one.  If there aren't protections in the law against such actions by the police, then I am against it.

It's exactly as you describe it.  No difference whatsoever.  Unless it's 'legal to be illegal'.

There are indeed such protections.  That doesn't mean a bad/cocky cop couldn't abuse such protections, but that's the case even without this law.  Some have argued, not without merit, that the temptation to ignore such protections was greater before this law was passed.

The states enforce it once you set foot into their state.  The feds are supposed to enforce it at the border (that Arizona is a border state is immaterial).

How can the feds disrupt?  So you are not the only one confused.  You would think the feds (who have the Border Guard plus the FBI) would welcome local law enforcement assistance, and in most cases they do.  But this is not about the law (it is in black and white), but Politics.  The Obama administration is playing the race card for its own political gains, nothing more.  So yes, the feds are objecting to states doing their jobs.  And the feds are not doing their job.

The feds have jurisdiction to enforce federal laws in all states.  There just is not enough of them so they rely on the state constabulary to do most of the work.  The crimes will be prosecuted in federal courts, not state, but it does not matter if Smokey The Bear arrests you or the G-Men.  The crime is the same.

The (apparently unrecognized) irony in this is just breathtaking.

Duh!  Doh!

Once arrested a background check is done through the NCIC computer data base. Finding out if the person is American born is not that hard thanks to DHS. A simple check of your SSN and we can pull up your entire life. The problem is that so called "open cities" make it easier for criminals to live and thrive in the US. In those cities if I get popped for say selling drugs and hint that I might be illegal then in a lot of cases I get the minimum and sent on my way. Whereas American citizens would go to jail. That is discrimination!

Again, that is State authorities' responsibilities to enforce among their own policement the checkup of everybody arrested. I don't mind that, you gotta know who is the arrested person.

Seems to me the legislation will allow policemen to do this to people other than those who are arrested.

When you get pulled over and asked for your paper, it's because you are driving a car. Driving a car in an inrhently (?) dangerous activity that might cause harm to you or the people around you if you are not careful. This is why we disallow people from going too fast. Or driving and drinking. Or some people are 100% disallowed to drive, period.

But there ain't any danger related to the activity of... well, you know, being. Can a policemen simply ask me for my paper while walking down the streets?

Obama is doing a wonderful job at this by putting "fear" into peoples minds over this bill. It's amazing how people will bitch about "fear tactics" but will ignore them when their own party uses them. Obama is praying on the concept of "this might happen" as a way to insult the Arizona local Gov't for basically making him look bad because, as has been pointed out, this bill was passed because the Federal Gov't did nothing to fix this problem.

Do you consider people crossing into our country from, say, Mexico without going thru the proper channels illegal? If so, please explain how you would not want to go after someone who is obviously breaking the law? Also explain how you could find out if someone did break the law without asking for some form of identification?

Do you think it's some form of discrimination only because those being questioned are Hispanics when the ones crossing the border illegally thru Arizona are likely to be Hispanics since Mexico and South American are Hispanic nations for the most part?

I would simply like to hear a decent solution of how to catch a criminal (because breaking a law makes you a criminal technically) that can only be found if questioned without inconveniencing the innocent.
