This is why jury nullification exists. It does not matter what this man does in retaliation he has been failed by the system so it's not guilty.

Lawyers should be the least of their worries...

Thankfully, we are not aware of any harm to the student because of this mistake

You're simply not aware. That is not the same as no harm occurred.

I told my kids they could walk out of school and call me if they had any discomfort with covid shot clinics on campus. Go out the door and keep walking, and I'll pick you up. High school age kids

So many questions , but - Who was the person that issued the name tag?.

Seems being issued name tags was for the schools vaccination event?

The child whose name tag it was, had already been vaccinated earlier that day - but they didn't mark off the name tag or separate it out as vaxxed ? How were the name tags verified to the child ?

Unless both children had the same exact name (and even if they did) then the individual giving out the name tags and not verifying them correctly with each child should be getting the short rope.

A hard way to learn that schools aren’t helping your child, they’re hurting them. Mostly emotionally and cognitively, but this is an example of how they can physically harm your child. Pull your kid out of school. Public, private, charter, it doesn’t matter, pull them out now!

But the school's principal can be held accountable...
