I think all this reeks of anti-Islamicism and paranoia about terrorism.

Shootings at American schools have been the work of schoolkids, acting as individuals. Preventing it should not be considered counter-terrorism - the phrase War on Terror has clouded judgement. This is the paranoia about terrorism part. This paranoia is concerned with Muslims. PC prevented them from naming this fictional group the Muslim Jihadis or the like - so they chose 'New Crusaders'. This name clearly reflects a mindset concerned with terrorism as a function of a religious clash of civilisations.
It's useless in this respect, and counter-productive for the safety of America's schools.
