But that is exactly where this line of reasoning will take you.

If you don't take "reasonable precautions" then you are liable.

I will also note that I often see comments here talking about living in SF and how they leave their car unlocked or windows down to limit the damage from thieves smashing the windows to get inside.

So with this "reasonable precautions" line, everyone who does this should be liable for promoting theft.

In my country, thieves removes your wheels, break your window, etc. Any electronic or hacker approach is very advanced.
