If this guy was worth a damn he'd resign over his part in the cluster,

and say "We need an outside group to do a full investigation of this."  
Fat Damn Chance.  
And most of our Professional Journalists don't want to touch it, it seems.
Here are just a few inexplicable things he revealed:
the Secret Service had no radio communications not only with the local police but also with the snipers

most of the vital communications were made using texts over an overloaded cell phone network

There are no recordings of the Secret Service communications, although there are of the locals

Rowe's assertions about the responsibilities of the local snipers didn't actually come from the local snipers--it was just made up by the Secret Service (we would know much less were it not for the locals)

the Secret Service command center was not co-located with the local police

The investigators have YET to talk to the local police who were assisting the SS, including the snipers (after three weeks!)

Butler was the VERY FIRST TIME that the Secret Service provided snipers for a Trump rally this election cycle

hmm, on that last one...
And, oh yes, there's more.
