And one result was to fill up the blog through mid-January.
I think I’ve been doing enough blogging recently, so my plan now is to stop for awhile and instead transfer my writing energy into articles and books. We’ll see how it goes.
Just to give you something to look forward to, below is a list of what’s in the queue. I’m sure I’ll be interpolating new posts on this and that—there is an election going on, after all, indeed I just inserted a politics-related post two days ago. And other things come up sometime that just can’t wait. Also, my co-bloggers are free to post on Stan or whatever else they want, whenever they want.
In policing (and elsewhere), regional variation in behavior can be huge, and perhaps can give a clue about how to move forward.
