There might have been DPS staff on site in Uvalde, but I assume it's like everywhere else in the US where when state law enforcement arrive they are there to assist locals and don't automatically assume control of an incident. TX legislators might be rethinking that whole protocol.
Local politicians are trying to cover their asses, this could be the end of their careers. Three local law enforcement agencies were involved: school district police, city police and county sheriff and they f'ed it up all by themselves.
