Because that's MY shop, actually, as much as the Sorc's shop. It isn't a guild location, it's a city one.
And my reclaiming of items that belong to me to begin with is a _defensive_ action, dp or no. The breaking into the shop and theft of items was an _offensive_ act, which is something I would not nor never have done while dp.
I think most will understand the difference, even if you choose not to.
