States seek to copy Arizona immigration law

This story is about 15 states in the US that are pushing to get the Arizona immigration law passed in their own state. Arizona law said if any one seemed like they were not of the US they can be jailed until they are found legal or not. To me i believe that its unconstitional to some extent. I can see that if the person that you caught and jailed was actually a US citizen then i can see there being problems with racial profiling and so on. But i also believe that we do need something along the lines of this law. There is tons of illegal immigrants and the only way they are caught is if they are jailed for something else and then they get deported. So i think that we do need to step up our law inforcement on illegal immigrants but not in the way Arizona purposed. To me these other 15 states that are trying to get this law passed should revise it alittle to get it alittle more constitional to the immigrants that are here legally.
