Not necessarily lazy, but as folks here so often have noted, if you think you are some place where something might happen, leave or move, but we can't spend our lives leaving and moving away from places that have become seemingly or apparently unsafe. It isn't that it would be lazy, but totally impractical. I know I can't live my life only going places that are "safe" and my safe neighborhood had a murder in it just a few years after I moved in. It was nice that I had a cop for a neighbor, but he was the one who did the murdering.
Also, it would drive some people nuts to continually consider the fact that they are not living in a place that is as safe as they would like.
