Can Twitter Lead to Crime?

On the way to work this morning, I was reading the metro and I came across an article about how twitter updates can increase crime rates. There was an incident where a guy had mentioned he was going on holiday for a week, which lead to his house being robbed. What are your thoughts on this? Is this a serious concern. I personally lock down things like twitter and facebook so only people I know can see my posts. Does this mean as a result, the full features of the tools are not being embellished?
