I think some of it is just that we as a community are self reporting ALL occurrences, so it feels higher than normal. I thought someone recently posted up stats showing the trend is going up though. I feel like another component, in addition to what had already been mentioned, is similar to what we see with "mass shootings." Meaning that since it's retorted in the media more frequently, that it's becoming the "thing to do" for career criminals. Very unfortunate.
