Spying deadly chemicals from 30 meters [News]

Sergei Skripal, a former Russian intelligence officer who became a double agent for the United Kingdom, and his daughter, Yulia, weren't the only people affected by a nerve-agent attack in Salisbury, England, in March. Nearly 40 others were sickened, including three police officers who were hospitalized, one of them for more than two weeks. A swarm of hazmat-suited chemical warfare experts inspected every place the Skripals had been recently in the hope of finding out what happened and whether there was still a danger to the public.
