This is crazy stuff. I'm still numb from this. We may not personally know someone affected by this event, but almost all of us know someone who knows someone... This type of potential outcome is exactly why I skipped CES this year...had a weird feeling and I have too many kids that need me to be caught up in something like this. The numbers: 59 dead, 527 injured, 800 lbs of weapons, 1100 feet away... these are things that won't be forgotten. It isn't about gun violence - you can argue gun safety and the NRA and background checks and what if all you want, but it's too soon and I'm not going to get involved. To me it's more about mental illness than anything else. Get to the root cause... and it's not likely to be weapons..it's people, values, mental health, etc.
Risk. We take risks when we go to something like this. What do we do about the risk - what should we do? Well, we should plan with whoever we are with how we will respond if things go south. Point to a spot that you will all run to and meet up if shots are fired or knives are used or an explosion happens. Crawling on the ground may be your response of choice... probably not your best option, but that may depend on the situation.
Risk on projects is the same way, though with a much smaller true price than human life in an event like this. But planning for risk, risk avoidance, and risk mitigation. And if it seems too costly.... don't go. Don't take on the risk. Don't attend the event. Don't take on the project.
Much like hackers are a step ahead of us... always. Everything can be hacked so the best thing we can do is plan the best we can and react well if it happens. Unfortunately, the same now holds true to something like this. It won't stop me...us...from attending something like this in the future, but we will feel less safe every time from now on. And we will plan... at least a little.
