A few days ago, I went to the local fair with a friend. At the entrance, there are now metal detectors, and "absolutely no knives allowed". My friend carried a small pocket knife, so he had to return it to his car. No big deal, just a minor inconvenience.
Inside the fair, we visited a building with all kinds of vendors. One of them was selling kitchen knives, mostly large one, all laid out for anybody to grab one and start stabbing people if they were so inclined.
I was stunned and disturbed.
How is that for safety?
