and 16 when the cops are getting called to his house and he gets expelled. why can an 18 or 19-year-old not get a hand gun until they are 21 but can get an ar-15 or ar-15 type weapon? the difference is concei conceiveability. it s got a stock to it and a longer barrel. when the shooter took the uber to the school, he carried it in a soft case which a professional would have looked at and triggered us and said a guy just walked into a bank and it s the middle of summer and he s wearing raincoat and hat. it wasn t enough time or someone didn t recognize it. for so long people are talking about schools are too open.
