Meanwhile back at the incident ...
What news from the police at my local airport ? They certainly spend enough time in the LCY terminal parading their Uzi machine guns in front of everyone at the top of the escalator and trying to look tough. Here we appear to have someone with a substance which is illegal to possess in the first place, who has then discharged it and led to people ending up in hospital, quite apart from the gross disruption to the services. The police appear to know, by stating it was a passenger, who it was. So what charges have been made ?
