Are all burglars stupid?

Last week I was woken at 0.24 o'clock Tuesday morning by Securitas and the friendly lady on the phone informed me that the alarm had gone off at our office and asked what they should do about it. Naturally my response was to send a guard. Preferably a whole bunch of guards. Beefy ones with vicious dogs if they had any. Having been woken already that night by the dog and my daughter I was hoping for false alarm and an undisturbed continued sleep until 6 o'clock when I get up to walk the dog. There would be no such luck. 20 minutes later the nice lady at Securitas called again to inform me that there had indeed been a break-in at our office. So I had to get up, crawl into the car and drive off to work. When I arrived there were half a dozen guards and policemen who all scattered once I arrived leaving me with a security officer whose task it was to cover up the holes as best he could. It turns out that the burglars had found the one remaining weak spot left from previous break-ins. Apparently you can tear up a hole big enough for someone to crawl through in a steel door if you only have enough time on your hands and a good crowbar.
Now, here's the funny thing. Immediately inside said steel door there is a desktop computer. Not state of the art but also not fit for the scrap heap. One door down the hall from where they gained entry is my office. On my desk there was 1 item of value. An Apple Cinema 24" monitor. Next to it was a very much worthless old Dell laptop that I had for the sole purpose of running a piece of software that I can't get to work properly on my Mac. It was a very nice laptop when it was new, like back in 2004. I replaced it today with an Acer Aspire One netbook which is a wonder of speed and brilliance in comparison. It set us back around 200 €.
This whole thing reminds of the first break-in we had after moving to this address. We were in the same building but had a smaller office facing the rear of the property. An ideal spot to throw a rock through the window and grab whatever you find of value and run. These guys however drilled their way through an Assa state-of-the-art lock that according to some locksmiths should be impenetrable. At least, a trained locksmith would need 15-20 mins to get through it. Well inside they grabbed the first thing they saw - a couple of machines on display inside the front door. They must have been really impressed with the low weight. They were of course dummies. The police found the dummies in the bushes nearby the following day.
We have been broken into twice more in the 14 years on this address and both times they caused a tremendous amount of damage to lay their hands on really old and basic computers. Come on guys, like we'd ever leave anything of value lying around for you to lay your sticky little fingers on? Let me make it quite clear that THERE ARE NO ADVANCED COMPUTERS IN OUR OFFICES OUTSIDE OFFICE HOURS. And during office hours, any uninvited guests will be introduced to a variety of house pets belonging to the staff. Some of these pets have severe attitude problems by the way.
To finish off, that Tuesday night I arrived home again at about 2.25. Fell asleep around 3 a.m. Was woken by daughter round 3.40 and finally woke up at 5.45. I was not too productive on the following Wednesday as you may guess.
