Life & Limb

What do you think about the following?

Life and limb does not become less worthy of protection by the law nor a loss less worthy of compensation under the law because he has come upon the land of another without permission or with permission but without a business purpose.

What if someone breaks into your home and is injured by some unforeseen trap? According this this, he can sue you for damages resulting from the injury.

Is that fair?

Is all life and limb worthy of protection?
