Unfortunately, we in <describe your region> have been victimized by <nature of unpleasant act> in a way that makes us all feel angry and violated. We thought that such problems were only for other areas, but now we know that we're all vulnerable. We at Abc Company wish to let everyone in <describe your region> know that we condemn these actions and will work with the community in any way necessary to see that such things do not happen again. This is our home as well, and we intend to help make it a place worth living in. Thank you for your time.
