I now have spare keys hidden outside my apartment
Which no complex kid/bored teenager/etc could ever find and use to rob you.
At which point, no doubt, you'll be dailing for the police.
Regarding your daughter and given the update you provided, would she accept an apology from the rookie cop and the police department?
You wrote a rookie cop was looking, he thought, for a kidnapped young girl.
Besides, and I'm not denigrating the injustice done, her privacy being violated, was she harmed?
Don't get me wrong, I'd be p1ssed if this had happened to me, but the cop did leave his card (he didn't have to), the police admit they were wrong, and they were, according to your account, looking for what they thought was a kidnapped child. In those circumstances, I might be inclined to accept the apology.
So, would a public apology suffice or will a suit for a substantial amount follow? With the payment coming from the city's tax revenue which otherwise might go for other police, parks, etc, etc.
Curious as to the course of action you recommend to your daughter.
