Is it my imagination, or are we seeing more of this lately?
This from KOMO News in Seattle:
A group of thugs (from the story, at least one of whom was black), attacking tourists downtown.
This from Fox News:
The Virginia man who murdered two TV news people, on camera.
Just today.

From what I remember of the statistics, it’s just hitting the news more– probably because you’re more likely to get video.
