In recognizing the fact violent attacks on Americans are multitier for the deaths the killer(s) seek, Governors should put the National Guard on alert when one occurs. It just seems to me the larger assault on emergency responders and/or a disabling bomb threat called into a hospital, the killers are measuring the response and it's limit in order to exploit those limits. Given the threats by terrorist groups against the USA there could be a larger problem hidden within the initial attack.

I would expect leaders of the global community would plan for such blossoming of attacks in a country. If a mass killing occurs there is every reason to believe there are more innocent people in the plans of terrorists. While police can handle most if not all of the danger lone wolf attacks, there may be a larger picture that might overwhelm that capacity.

At the point where the National Guard in the USA would actually be deployed it would be nothing short of declaring a police state. That would be the discretion of others, but, I think those scenarios are a matter of preparedness as well as the drills first responders practice on a regular basis..

Homeland Security should provide workshops for Governors that would place them in a scenario where the National Guard would be deployed and a police state is possible. I just think the USA can't be too careful considering the danger that played out in San Bernardino.
