An estimated 1,000 protesters rallied in Union Square Friday afternoon for a May Day rally for worker and immigrant rights. People gathered in support of issues from raising the minimum wage to fair and equal pay for women, but this year May Day meant a lot more to many people-with the death of Freddie Gray, the subsequent violent protests in Baltimore, Maryland, and the indictment today of six police officers in connection to Gray’s death, racism among the police was one of the main messages, if not the most prevalent issue, taken up by the protesters.
