Re: The right thing to do
It is not simply that they are swatting flies with a bazooka.
It is that this whole exercise was useless. We know it, they know it, and Mr. Lindon knows it, but organizations are desperate to look like they are doing something, while in reality helping nothing to eradicate the real terrorism/insecurity problem.
It is a highly visible move that allows them to say "we take the security of our guest very seriously", but is it conductive in any way to actually make Las Vegas, or USA or the world any safer? of course not.
It is the same train of thought that leads corporations to fire people because of a stupid joke they did years ago as if that helps to fight the rampant sexism and abuse in the industries.
These actions are hateful because they are nothing but PR at the cost of a person that everybody knows is innocent. If (or $Deity forbids, when) the next attack occurs, this stupidity will help nothing to prevent it.
