You say it can't happen?  It has already happened throughout history, more than once! (excerpts):  Washington - Indefinite military detention of Americans became the law of the land Saturday, as President Barack Obama signed a defense bill that codified that authority.  The National Defense Authorization Act states how the military is to be funded, but also includes a number of controversial provisions on arresting and holding suspected terrorists, which at first drove Obama to threaten a veto.  He retreated from that threat after Congress added provisions that took the ultimate authority to detain suspects from the military's hands and gave it to the president.  The signing on New Year's Eve, as few people were paying attention angered civil liberties advocates.  "President Obama's action today is a blight on his legacy because he will forever be known as the president who signed indefinite detention without charge or trial into law," said Anthony Romero, Executive Director of the American Civil Liberties Union.  "The statute is particularly dangerous because it has no temporal or geographic limitations, and can be used by this and future presidents to militarily detain people captured far from any battlefield," Romero added.  The Obama administration was especially sensitive about the law and about reaction to the president signing it.  In addition to enacting the measure while few people were paying attention - and many opponents still had hopes the president would veto the bill - the White House added a signing statement specifying that the Obama administration would not detain Americans without a trial. 

Commentary:  It is clear to see how that Congress and the Obama administration are cohorts to pass this law while the world is celebrating the New Year, underhandedly; and this "statement" that he will never actually use the law that he just signed, ridiculous!  As if everyone is supposed to be so stupid as to believe, "Oh, he signed the bill, but since he said he won't use it, everything is okay then.  Ridiculous and absurd!  You have to ask yourself, "Why would the president sign a bill that he says he won't use?"  What is the sense in that?  In fact, he has signed so many unconstitutional bills, while including "signing statements" that he won't use them, the "signing statements" can really get lost in the shuffle!  Unconstitutional bills should never be signed - period!  They will be used, you can believe that.  He is only trying to detract guilt away from himself, as he signs into law these unconstitutional bills.  Here are a few alarming bills and resolutions enacted or proposed since 1991:

1)  The Noahide Laws resolution signed by Congress - 102nd Congress (1991-1992) H.J. RES.104 ENR
2)  Georgia's HB 1274 - Death penalty; guillotine provisions
3)  HR 3590 Healthcare bill, including the Patient Protection and Affordable Care Act, which regardless of what Snopes says about it, will bring about an RFID chip under the guise of patient privacy
Hate Crimes bill, which actually allows for prosecution of people, such as pastors, who speak against homosexuals, or possibly others living immoral lifestyles, and it does away with our First Amendment Constitutional right to freedom of speech in such circumstances
5) NDAA National Defense Authorization Act, indefinitely detains US citizens without a trial  

As you can see with these few examples, there is a steady, long-term movement to destroy our liberties and Constitutional rights.  The Bible tells us that there will be a dictator in the last days, who will mandate that everyone on earth receive a mark in their right hand or forehead in order to buy or sell.  The Bible also tells us that there is no hope of salvation for those who take the "mark" of the beast (Antichrist).  He causes all, both small and great, rich and poor, free and bond to receive a mark in their right hand or in their foreheads, that no man can buy or sell, except those who have the mark, or the name of the beast (Antichrist) or the number of his name.  Here is wisdom.  Let him who has understanding count the number of the beast, for it is the number of a man and his number is six hundred, sixty-six" Revelation 13:16-18.  "The third angel followed them, saying with a loud voice, If any man worships the beast and his image and receives his mark in his forehead or in his hand, the same will drink of the wine of the wrath of God, which is poured out without mixture into the cup of His indignation, and he will be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb (Jesus Christ - the sacrificial Lamb), and the smoke of their torment will ascend up forever and ever and they will have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name" Revelation 14:9-11.  That's pretty clear and final, and as sure as there is a God in heaven, it will come to pass.
