//"Have you ever been arrested or convicted for a crime that resulted in serious damage to property, or serious harm to another person or government authority?"//
There's two problems you face when answering that question:
1. Its interpretation. As mentioned, it could have one of two meanings. Interpretation #1: have you ever been (a) arrested or (b) convicted for a crime.... etc. Interpretation #2: have you ever been arrested or convicted for a crime...etc.
2. "Serious harm" is subjective. Somebody who had been the victim of harassment may well consider they had been the victim of serious harm. Harm is not exclusively physical.
Best to contact the US authorities, tell them what the situation is and ask them to rule on it.
