I will grant you that some defense is better than nothing; so maybe if I am looking at this with my “the glass is half full” hat on, this could be seen as a positive improvement.
In the latest DHS video, our trusty narrator says “If you are caught out in the open and cannot conceal yourself or take cover, you might consider trying to overpower the shooter with whatever means are available.” Finally some common sense advice to stop some madness. It is not going to be everyone who can rise to this level, but if we all cower in fear, the bad guy gets to get away with whatever he is doing until he is stopped.
The video even goes through an explanation of the differences between cover and concealment. Most of the focus seems to be on getting out of the building or hiding, but I will choose to believe that some mention of an option of stopping the shooter by whatever means is necessary is a step forward.
Now, if they talk about carrying concealed and how to engage in the next video I will probably fall off my chair.
