im actually surprised they dont make people pass a stress test before doing it
You mean, make people who want to take a rifle class, pass a stress test? I'm not sure how you would do that ... this was a 60 year old male who seemed healthy and was able to do drills, run, etc.
You never really know what could happen. My dad had a heart attack back in 1996, while staying with my brother and his wife and kids, in the South of France. He shared a bedroom with one of the kids, who was still very young at the time. Kid woke up crying around 3 am, which in turn woke up my dad and my brother. That was fortuitous because a little bit later, my dad had to sit down complaining of chest pain that radiated through his arm. Before you know it he passed out. Brother calls 911 (actually 112, the European equivalent) and 2 minutes later the local French fire department medics came rushing to their holiday home (God bless them). They had to rescuscitate him twice with a defibrillator before they could get to the ER. He had no prior heart health history. Things happen.
