This tweet, while in bad taste IMO, was a threat to those who are planning to continue looting and burning buildings in Minneapolis.
I’m not sure if you’ve seen the videos, but there are full scale riots. Rioters completely looted a Target and burned it nearly to the ground.
Is “shooting” the answer to that? Probably not. And hopefully the National Guard is not going to do that.
But at the end of the day, this is the commander in chief making a public statement, and Twitter is editorializing it. Make of that what you will.
...neither of which is an outcome in this situation, and looting is not a credible treat to people's lives.
First, are there circumstances in which a citizen could apply lethal force to protect life and limb? Obviously yes; shooting someone trying to light your house on fire is certainly something that is both plausible and plausibly legal.
Second, is it appropriate for the political leader of a nation to imply that people committing a crime will be shot for it on the street? Not "we will deploy the national guard to provide safety and security to the citizens" but "looters will be shot". I think the answer here is obviously no, that is not appropriate.
I will also add that this is also a case of tensions boiling over. While that doesn’t justify the arson, meaningful reform to defuse long standing tensions would be a wise move.
