I'll start off and then perhaps people who have more specific information can jump in.
I admit that I am only aware of these cases through the media reporting, and I take everything I see in the media with a relatively large grain of salt. I'm pretty certain there were these police incidents and members were barricaded inside their homes, but I don't know anything specific about what was going on in their lives at the time, other than that they were on the list for rotation. There's a whole lot of unknown information in the background.
