Schools today are very good about teaching tolerance and acceptance. Once in a while something may need some correction.
I don't see anything that shows this was ethnic profiling.
News sensationalized it. Internet exaggerated it.
My opinion the school gets a chance to deal with it.
The PTA can get involved to discuss it. The community gets involved with various groups if needed.
The whole incident worked out at the community level and the 14 year old gets to live his life without being constantly reminded that something bad may have happened to him because of his ethnicity which probably didn't happen here anyhow.
I was pretty impressed with the clock this kid made. Nice to see some interest in electronics hardware these days.
