It reminds me of being back in law school. There was a case about the individual who dug a pit because people had been trespassing on his property, and the next person dropped 25 feet down into some sort of a pit.
That wasn't reasonable when I was back in law school three decades ago and it's still not reasonable today.
The test of what is reasonable under the circumstances, as you quite correctly pointed out, has changed over the years, but it's what most people feel would be appropriate.
Many of us have alarm systems in our homes, and we try to take precautions, but having booby traps that could maim somebody...I think most people would conclude that's not reasonable under the circumstance. You might have somebody delivering pamphlets that you didn't want to see. We can't have that kind of situation.
Did you want to add something, Ms. Klineberg?
