I think he is making a point you are taking too literally. It is a death squad. They shot a man in cold blood and executed him. This is an assassination. True, they aren't indiscriminately mowing people down. But they are testing the waters and achieving their desired effect. More to the point, we have all watched too many Hollywood movies so we don't stop to consider basic things such as how many 48 year old men do you know who can run with a gun? This is a skill. They were in and out very quickly, which also is not 'normal'. Where did this training come from? Who paid for it? These are the questions we are finally starting to ask.
