Well it appears that Starbucks has created a serious problem that for most people had died down.
There are a minority of people in the US that truly believe that Gun Control works, just ask any of the families of the victims of violence if they wish they could have been there to shoot the person responsible for the death of their loved ones.
The last few years all the gun controlled areas have been an open invitation that virtually guarantees a criminal that they will have little fear of an armed confrontation if they go to these places.
It is acting stupidly.
Why is it that we have had more incidence of these types of problems now than we had from 2002 to 2008?
When you appear weak, when your security is lax, when you have signs posted that tell criminals that they can operate without fear of being shot, this is what happens.
The real shame here is that people like the git, in charge of Starbucks continues to think that they can ignore the majority of its customers in favor of the minority of its customers.
