I believe the count for Maryland alone is now six: that is, six kids who were (I'll use the word) bullied by public school and law enforcement officials because they dared to refer to guns. This latest from Owings involved a boy who was merely talking about guns. Again this happened on a bus. The 11-year-old was questioned by a Sheriff's deputy, who wanted to search the family home - without a search warrant, of course!
The WMAL article is here. I don't always agree with the ACLU on various topics, but I must commend them for taking a stand against this overreach of authority and abject silliness on the part of school administrators, bus drivers, etc.
