Hi, first time posting. My eldest is due to visit London on a school trip. An worried that the current terrorism threat level is 'severe'. Should I allow him to go? I'm not usually prone to panic etc but have a nagging doubt that won't go away. I've asked myself 'where is he safest?' The obvious answer is at school and not in Central London. I know the spiel about not letting terrorists prevent us from going about our everyday lives but is it irresponsible to allow your child to travel to a city when the threat of a terrorist incident is 'highly likely' (in the words of govt advice).
