He did send it to someone. He snapchatted it. Somebody took a screenshot of the snapchat and put it on twitter. Then the school saw it on twitter. nobody's free speech was violated
Honestly, as a parent, if the school did nothing they would be in big big trouble. Imagine if the shooter of sandy hook posted a picture and ambiguous comment on twitter before his attack. The school saw it and did nothing b/c they incorrectly thought it would violate free speech. wowzers
The school acted appropriately. Tough lesson to learn. Once you send something to somebody else, it is public. The school's first priority is to keep students safe. they did that.
I assume you think suspending someone b/c they called in a bomb threat to get out of a test is a violation of freedom of speech?
