Lois complaining about a reporters integrity? That's just hypocritical considering who she married.
And what exactly is Cat doing wrong here? Everything she said is true, Supergirl has acted out-of-control and as a menace. She attacked Air Force One, has attacked other heroes, tried to kill Superman, has stopped cop-killers from being brought to justice and generally been a screw up. Plus her current actions are incredibly hypocritical.
