"Historically courts in this country have been insulated. We do not look beyond our borders for precedents"

This quote by Sandra Day O'Connor is referring to the judicial system in the United States. She is stating that historically, courts in the United States have actually been separated from other nations and have actually not wanted to other countries for assistance or precedents when making decisions. This remains in contrast to other nations, such as the UK, which typically looks to other nations for guidance when making decisions. O'Connor is emphasizing the significance of the United States judicial system being independent and not depending on other nations for assistance. This independence permits the US to make choices based upon its own laws and worths, instead of those of other nations.
