Andrew, interesting observations. I just found out that a local gun range has had three incidents in the last year where guys have come in, rented a firearm, gone into the shooting lanes with it, loaded it and shot themselves. So while the suicide rate overall might not be up, stories like this one certainly are. We've also had several barricaded police incidents recently in the immediate area (not necessarily where I live, but close enough that it made the local news), and those usually start out as domestic violence.
I do think that the pandemic has probably had a "delaying" effect on a lot of MR in crisis. As you say, the opportunities for infidelity are down, and humans tend to be very opportunistic creatures. I remember when I worked in retail the loss prevention team would always tell us the important of being on the store floor, making rounds. Because they said that 15% of people will never steal, no matter what. 15% of people will always steal, no matter what. But 70% of people will steal IF they think they can get away with it. So having a presence of employees in the store would discourage that 70%. That has always stuck with me.
I say "delaying" because like you point out, there will always be MR problems. Many WASs are probably biding their time until things normalize. However, I would think the incidence of EAs is up right now.
