My girlfriend went to the United States. Is the public security at Yale University in Connecticut good?

Connecticut’s public security management is increasingly in the stage of improvement. As one of the eight Ivy League schools, Yale University’s public security aspect cannot be ignored. In addition to the security department, the university also provides escort services and shuttle bus services to protect personal safety. From the 1970s to the 1980s, the poverty and crime rates in New Haven increased, which worried Yale teachers and students. Later, from the 1990s to 2006, the city's crime rate was halved and safety problems improved greatly. This was largely due to the efforts of local police. Yale has also become a member of the Ivy League with the highest campus security.
