A more thorough explanation:

The Support Our Law Enforcement and Safe Neighborhoods Act of 2010, also known as S.B. 1070, was a controversial immigration law in Arizona. It was created to address the issue of illegal immigration in the state, which many believed was causing an increase in violent crime rates.

The law contained several provisions that were highly criticized, including allowing police officers to arrest individuals based on suspicion of being in the country illegally. This provision was seen as potentially leading to racial profiling and discrimination against certain groups.

Despite legal challenges and criticism, some parts of the law were upheld by the Supreme Court, while others were overturned. For example, Section 3 of the law, which made it a misdemeanor for immigrants to fail to register properly, was found to be preempted by federal regulations. Section 5(C), which made it a criminal offense for an illegal immigrant to work in Arizona, was also overturned because Congress had not imposed criminal charges for this offense. Section 6, which allowed state officers to arrest immigrants based on suspicion without a warrant, was also found to be preempted by federal law.

One provision that was not preempted by federal law was Section 2(B), which required officers to check the immigration status of individuals they stopped or detained if there was reasonable suspicion that they were in the country illegally. However, this provision was eventually repealed in response to lawsuits by civil rights organizations.

The Support Our Law Enforcement and Safe Neighborhoods Act of 2010 remains a controversial piece of legislation, with some arguing that it unfairly targets certain groups and others arguing that it is necessary to address the issue of illegal immigration.

An example of the controversy surrounding the Support Our Law Enforcement and Safe Neighborhoods Act of 2010 is the case of Arizona v. United States. In this case, the Supreme Court overturned several provisions of the law, including those that allowed officers to arrest individuals based on suspicion of being in the country illegally and those that made it a criminal offense for an illegal immigrant to work in Arizona.

This case illustrates the legal challenges and controversy surrounding the law, as well as the tension between state and federal immigration policies.
