People will do that here. Most recently for the southport officer who was killed. Also look around for blue porch lights. That started by someone right here on ingo actualy and is now nationwide.
Did not know this, but recall the rash of blue light avatars when I first started noticing this. Definitely happens here in MA. I know a Satety or 2 and they have the blue out much of the time. As do some of their neighbors as you might imagine. Red for firefighters now too.
When did this get started and what member, if I may ask?
