http://www.wlwt.com/news/18835788/detail.html Wade Nassar was the same shopkeeper who drove a robber out of that store with gunshots back in 2007, and was praised rather than charged with a crime, as you may recall.
That is in the very core of Cincinnati and the area is well patrolled by police. They will take great pains to catch the perpetrator whenever something like this occurs in downtown proper. So, what would make you think this can't happen in
your part of town? (That's a rhetorical question!)
To me this is just a reminder that one must stay aware at all times. If you don't keep your head "on a swivel", someone will chop it off and stick it on a pike.
