Now there are different groups of people who are predicting violence and feeling the need to do something about it. Too early to tell whether the fears are overblown this time around as well.
In any case, I hope all first-time gun owners properly train with them and secure their guns at home. I wouldn't be surprised if the main outcome of both of these clusters of gun buying is not actual defense against the feared threats, but that guns get stolen and used for crimes.
