VIDEO: A CBS 5 investigation found used hypodermic needles left near light rail stops, city parks and public restrooms. Advocates for homeless drug addicts say there is more that government officials can do to protect the rest of the public. This is an issue the firefighters at Phoenix’s Station 18 are all too familiar with. “Bathrooms, restaurants, fast food places, bus stops, light rail stations,” said Capt. Kevin Duzy, who has seen drug use, drug paraphernalia and responded to overdoses at all of the places he mentioned. “You never know where you’re going to run into, you know, dirty needles or paraphernalia. It could be anywhere in a public place,” said Duzy.
