They left the car unlocked in the same sense that your home is unlocked. With the right tools, it’ll take me 5 minutes to gain entry. I could then claim that it’s your own fault I gained entry because you don’t have a metal enforced door, steel bars across windows, and a lock that can’t be easily or Hardily picked...
Yes, someone technically minded with the right tools and access can break in. But that’s less than 5% of the population, very similar to the percentage who could easily pick even a complicated lock, but Of cause near 90% will be able to take an ax to a door or kick in a window.
Someone who snatched a purse out the hand of someone else isn’t “doing anything special” either. The illegality doesn’t hinge on the difficulty of the action. Why is that so hard to grasp for technical crowds?
If you find a car with the keys in the ignition and the door unlocked, you won’t get away with driving it a block down the road by telling the judge: “Oh, but it was obviously insecure, and I was just testing to see if I could steal it”.
