I also think Sullivan was given his due praise in the article for having the sagacity in educating his officers. Many LEOs never admit mistakes and do not change protocols unless they are absolutely forced to do so.
In our current environment, and in my opinion, corporate security should be taken out of the loop between law enforcement and the crews.
A real problem that has to be addressed in some fashion is the crews don't trust law enforcement and law enforcement does not trust the crews. That is a situation that will ultimately be exploited for ill if not fixed.
