When you head to the beach, you expect to find some leftover sandcastles and nasty sunburns - not a tide of used syringes. But that’s what was found on the coast of New York, New Jersey and Connecticut in 1987-88. It destroyed tourism and caused drastic changes in local waste disposal. It’s a horrifying thing to think about, but what we didn’t realise is how often this still happens. Medical waste disposal is a huge issue for anti-pollution campaigners, so to learn more about it all, we’re talking to Ruth Stringer, International Society and Policy Coordinator of Health Care Without Harm.

Ordinary guy turned vigilante icon, Bernie Goetz shook a crime-riddled New York City in 1984, after he shot 4 black teenagers on the subway. It created a rift within public opinion, and forced difficult conversations about race, self-defence, and gun rights. But when does self-defence go too far? How do we know Goetz truly felt threatened by teenagers he suspected would mug him? And was he properly punished? This week, we also explore the current case of Jordan Neely, a homeless black man who was recently killed on the subway after being placed in a deadly chokehold. It draws eery similarities to the Goetz case, so what does this say about the current state of America? Has anything changed since Goetz? Learn more about your ad choices.
