Who this "expert"? He doesn't seem to know much about criminals. I suppose he'll probably also say that car alarms need highly skilled IT experts to break and therefore it's unrealistic for cars to be stolen without actually breaking a window as criminals are stupid. It's the "expert" who is stupid. He probably advised the car makers when they were making their insecure car alarms.
This "expert" needs to realise that not all criminals are clueless. Criminals can come from all walks of life.
