RISDAlert: Critical update. Police activity reported in the area of Brook and Thayer Streets. Avoid until further notice. More info to come.
RISD's first notice at 4:28 p.m. EST described only 'police activity' and an instruction to avoid the area, six minutes after Brown's own 4:22 p.m. EST alert had already used the words 'active shooter,' according to The Brown Daily Herald.
Because the two campuses on College Hill physically overlap but run separate notification systems, a RISD student near Brook and Thayer could be feet from the danger zone while reading a far less urgent message.
Verbatim text confirmed from WPRI and Brown Daily Herald reporting; both outlets published this exact alert text.
