It does depend upon your usage of the word because for many people the common parlance definition of crime is to do something against the law, rules, regulations, etc... not a specific legal definition.

Words and their meanings are important, but so is flexibility in attempting to interpret their underlying meaning.

No, people distinguish pretty clearly, even in common parlance. Nobody in common parlance would say you're a criminal for speeding by 5mph.

I don't think they committed a crime, but my knowledge of UK law is limited and reading the Order and the Act didn't immediately lead to an answer. I'm happy to be shown wrong.
