In checking Target's website, the "request" not to being arms seems hinged on "open carry" practices, but it then goes on to read like concealed carry will be covered as well.
From the Target website:
As you’ve likely seen in the media, there has been a debate about whether guests in communities that permit “open carry” should be allowed to bring firearms into Target stores. Our approach has always been to follow local laws, and of course, we will continue to do so. But starting today we will also respectfully request that guests not bring firearms to Target – even in communities where it is permitted by law.There's a Target store near me. A young mother was gunned down in the parking lot a few years ago. In the same shopping center, a father who was carrying a pistol was able to thwart a carjacker last year.
And Target wants me to disarm?
I suppose I should ask how forcefully Target will enforce its "request" that patrons only come if firearms free.
When my concealed firearm and I were welcome, I occasionally spent money there. I won't be shopping there as long as Target wants to advertise itself as (or even imply it is) a gun-free zone.
Gun-free zones often attract the wrong kind of people.
