seems to me this is somewhat similar to the time honoured tradition of trying to read the entrails of sheep in order to predict the future.

Violence depicted in adolescent political cartooning perceived as a security threat? What a bunch ignorant, provincial, paranoid boffos.

Fortunately, when my daughter was in school, she was fairly adept at figuring out which teachers knew the difference between education and indoctrination and which ones didn't, prior to presenting her work. Unfortunately some kids learn the hard way. That the drawings would be brought to the attention of national security is beyond the pale.
