The kid has nothing to fear. Having a package and wearing a hoodie does not make a bomb. If the school called the bomb squad, they are the ones with egg on their faces, so they are charging him with a felony and hiding behind the excuse that we can’t be too careful in this day and age. So, they charge him with a felon because they called a bomb squad. I have only two words of advice for the young man: Jury Trial.
"Having a package and wearing a hoodie does not make a bomb."
So, if you observe a person wearing a hoodie, gloves; sneak into a public building (airport, school, bus stop, hospital - any building where unarmed, innocent lives will soon occupy) with a large wrapped package - what would you do? Go pick up the package? Kick it? Open it and hope it wasn't a bomb? The school did the ONLY thing they could do - with the evidence at hand.
A felony rap is a bit over the top - but this was a poorly conceived plan from the get go. If he had smuggled the inflated doll in - there wouldn't have been a problem. But sneaking a large box into a building - something should have gone off in his head saying "Should I really be doing this?". Funny? ... yup. Smart? - uh, nope. Try doing the exact same thing at an airport - and let me know how it goes.
Bingo. The prosecutor would be a laughing stock if he pushed this to trial.
