Oh yes, lets hang out at Starbucks with 25 George Zimmerman types looking for "suspicious" people. What you've got going on in Starbucks is a group people coming in carrying weapons for political reasons.
Why is it these "open carry" demonstrations don't happen in crime infested neighborhoods? Why make a point out of scaring people in neighborhoods where there isn't any crime?
Starbucks in Seattle was asked about about its policy on guns. They let guns in, but camcorders weren't allowed in. Does that make sense?
