It's crazy, the balancing act Giroux and co. must be doing, between X amount of shady stuff they know about or suspect but can't prove yet (and the hope that they will be able to in time), and the terrible optics of Ford walking around free, committing crimes, daring them to arrest him, making it look like all of TPS is in his pocket. Surely they are weighing the damage this is doing to their public image (like, I can't imagine Giroux wants to go out like this) against the arrest(s) they still hope to make.
