Kelly is not being genuine with the American people.
He's a 4-Star US Marine General and his late son was a Lieutenant in the US Marines.
That's not the same at all as the rest of the US Government First Responders such as the Green Berets and Kelly knows that.
First Responders have high-risk jobs but are not supposed to be killed on duty unless something really goes awry.
The US Govt is expected to do all it can to preserve the lives and human bodies of First Responders.
In contrast the US Marines have always taken impossible, suicidal missions.
Often only minutes notice , US Marines are deployed in an emergency on un-planned missions.
The deadly missions are as small as one or two men, and as large as 100,000 men.
