This is the same word games that edge lords use to avoid social consequences; there’s no “I was just kidding” excuse when the president of the United States of America discusses the use of lethal force on American citizens.

He is saying exactly that.

If they loot shot then, that's what he is saying.

It would be fine if it's: if they loot arrest them and if they treat to prevent this by using weapons like guns then you can shoot them if there is no other way.
