The school VP suspended a kid because he had a pen with a Glock Logo on it.
I'd show up to pick up my kid with my lawyer while wearing this shirt:

Then I'd give the VP a copy of 18 USC 242 and tell the VP I was going to visit the Federal Prosecutor next. The tone of my voice would scare him far more than the words I used.
In Moscow Idaho my daughter (above) actually wore the shirt you see above to school. She only showed it to one teacher, but still, he thought it was cool.
H/T to Uncle and Bruce.
