"a county employee that can't deal with a hostile customer"
From what I'm seeing the clerk did a good job of dealing with a *expletive deleted*bag customer (DBC).
Didn't get into a screaming match with DBC, didn't trade punches with DBC, told DBC what was going to/not going to happen, and when DBC wigged out about it, called the police to resolve the situation. To me, that's handling things properly.
Cop also seems to have handled it well. It would appear that DBC doubled down on his douchebaggery and refused to obey the police officer's orders. I don't care who you are, if you willfully ignore the orders of a police officer, things are not going to go well for you in the short term, even if it's determined that the cop was wrong (that's long term).
Also, the cop didn't shoot, tase, or beat DBC. Just arrested him.
Based on what's here, and what precious little I've been able to glean elsewhere, the only person to blame for the outcome is DBC. The cop is good, the tax office people are good, so there's absolutely no reason for the judge to be overstepping his authority and bring them up front for a scolding.
I think any judge who gets this case is going to be both amused AND annoyed, but it's going to be all directed at DBC.
