:: a parent demanding their right to be present if police want to question their child triggers prosecution ::
This is the most disturbing of your points.
I have consistently taught all my charges (children and SS students) to not answer without some type of counsel present.
Even a simple question during a traffic stop of:
“Do you know why I stopped you?” is prima facia collection of evidence and is protected by the 1st, 4th and 5th Amndt.
Don’t talk to the [currently militarized] police. Politely ask them to perform their duties as prescribed.
Search UTOOB for hundreds of lessons and examples.
I taught my kids the same thing. In Texas, probation officer is a large employer, they need to justify their existence.
“Do you know why I stopped you?”
“I’m not sure, officer, but is it because if I pulled you over it would be weird?”
