If the dog takes a poo in the house 5 times over the year, i would scold it and say "no,no,no, BAD dog" ...every time.
I don't need to go outside the other 360 days and tell the dog how good he is.
More importantly, we aren't talking about the garbage man forgetting your house, these guys go into the force because they want to help people (presumably) and they swore an oath to set the highest example unless i'm mistaken.
These aren't minor infractions here, this thread has more serious crimes than most novels.
Here's another analogy to simplify things, if you own a business, hire a loss prevention officer and he's the only one stealing from you, should he be suspended with pay? keep his job if he says he's sorry? Or be charged as the thief he is?
And if you have two dogs but punish the good one, when the bad one goes in the house...?
