Guerrilla Grafters - potential liability for CRFG????

Perhaps this explains the very large quantity of scions I saw a few young folks taking from the exchange last year. How do we ensure that CRFG does not become in some way liable if these fruit anarchists use our resources to graft edible "nuisance" varieties onto ornamental street trees??? How do we harness their youthful enthusiasm to do good fruit grafting works within the law?
