I may be wrong here, but I thought Arizona had more Hispanics than any other state in the US, except New Mexico. So the bill had to pass with atleast some Hispanic support. Also, I believe that no contact can be established with a citizen in order to determine if they are illegal immigrants or not, unless contact has been established due to some other infraction of the law. Unless the people being "profiled" actually do something illegal, they do not need to fear being questioned. In addition, I thought there was a standard, well defined procedure to determine suspicion for the police in the USA.
