Family Business

Bashir and O'Brien go through a lot of trouble trying to get into Quark's bar so they can retrieve their dartboard. Odo argues mildly against it, but does nothing. Er, isn't this attempted breaking and entering? Isn't that illegal? Why isn't he arresting them? And why not just use a transporter to beam inside? That way you're only entering without breaking, you might get a lighter sentence! You could even beam the dartboard out, thus avoiding both the breaking and entering altogether!
