I got a package the other day from an online order I had made. My wife asked what it was and I joked and said it might be a bomb, some dust with poison or a virus or something. We laughed at the thought but it got me thinking of all the packages I just open without thinking all the time. I would never know it was a bomb until after it went off in my hands.
Plenty of random innocent people have died from package bombs. All it takes is for someone to hate your boss / your neighbor / someone unrelated with the same name. Or just, someone unhinged
