Arizona Gov. Jan Brewer has signed into law Senate Bill 1070, a contentious immigration measure that gives police sweeping powers to question and arrest illegal immigrants.
Brewer made the announcement Friday at a press conference in Phoenix.
The law allows police to arrest illegal immigrants for trespassing in Arizona; requires immigrants to carry work and travel papers; and makes it a crime to transport illegal immigrants, including day laborers.
Brewer faced political pressure from both sides on this issue. The governor is running for re-election.
Public opinion polls show the majority of Arizona voters back the measure, with strong support from conservatives including Maricopa County Sheriff Joe Arpaio, who also is mulling a gubernatorial run.
Critics include those in the tourism industry, who are concerned that the law underscores a negative image of Arizona and could cost the state conventions and other major events. Phoenix Mayor Phil Gordon and others say the measure is anti-Latino and will lead to unfair targeting of those with brown skin.
im goin to make an unfortunate prediction here tho and
say that illegal immigrant violence rises because of it in the short term... go arizona, all that you need to do now is get the cochise county
militia down to the border..
