Documentation on the person

Instead of asking people to carry documentation like passports and green cards the government needs to spend some serious tax dollars in improving the border security. They have been spending quite a bit of tax dollars securing US in Iraq and Afghanistan without worrying about the Arizona, Texas, or California border for years. Or perhaps that is what we are supposed to believe dumb that we are. Carrying documentation all the time makes one feel like one is stuck in some airport for life. I do not understand why Americans are picking up fights with muslims, mexicans, etc etc. Some cantankerous people are in the office for sure. I do not understand how so many people can support this law in Arizona. Perhaps they do not understand that "every one" has to carry documentation because some one who looks American to one need not look so to another and that includes people from European shores too.
