Car keys

We were in American Fork the other day. We stopped at a Walmart and I managed to lock my keys in the car. Of course Ken had left his keys at home (Murphy's Law). We called the local police department for help and they came and got the keys out for us. The disconcerting part was how fast they broke into our car to get the keys out. It really makes you wonder if we should even bother locking our car. I guess it only keeps out the casual burgler, not the professional car thief.
