Whole situation is fukked from all parties.
Young bul shouldn't have brought what to the average lay person looks like a bomb to school. People are dumb as fukk. The average person wouldn't have been able to identify it...because really if you build a clock, why would you build it in something that's meant to conceal it. You can't bring toy guns or anything resembling a toy gun to school, you shouldn't be able to bring a toy bomb or what appears to look like a toy bomb to school.
However, protocol broke down on the school administrators and police's behalf. The first teacher that saw that shyt should have said put away in your locker after it was explained what it was. And maybe got the principal involved after class to verify. Most suicide bombers aren't walking class to class with an explosive. They blowing shyt up at the beginning of the day, the lunch room, or the let out.
This is different than the Trayvon's and Dudialo's...shyt looked like a weapon. If it had been a weapon, and it went off this would be a whole different conversation.
Kid deserves everything he's about to get because procedure broke down, and he didn't have to be arrested.
