From my latest article for CAIVN:
Starbucks, replying to a petition from a gun control group, has said it will not ban the carry of handguns in its stores, if permitted by local law. The controversy ignited in Walnut Creek, CA when members of Bay Area Open Carry, a group advocating the legal carry of loaded handguns, began carrying open, unloaded handguns at Starbucks (which is generally legal under California law, with some exceptions.)
The Brady Campaign to Prevent Gun Violence responded to this by starting a national campaign to have people sign a petition to demand Starbucks ban guns. Starbucks, so far, has refused. As you can imagine, this controversy has both the pro- and anti-gun control factions, well, up in arms.
