Protests continue in Baltimore, Maryland over the police killing of unarmed African American resident Freddy Gray. Yesterday evening demonstrators blocked traffic and protested in front of police headquarters. Authorities have still not released the full details on Gray's death but admit police had no probable cause to detain him. Many of the Baltimore demonstrators made the connection between Gray's death and a rash of similar police killings of African Americans in cities throughout the country in the past eight months. teleSUR
