Unlawful arrest
"Its called citizen arrest. If the have lawfully detain you for a crime and you run they can add resisting arrest ."
In the England and Wales a citizen only has the right to arrest if a indictable crime has is being or has been committed, or a person has reasonable grounds for believing so. Im pretty sure downloading a game to an Iphone is not a indicatble offence and no "reasonable" person would consider it to be hacking. Furthermore as the arrest would be unlawful in said circumstance, it would not be an offence to resist the arrest so long as reasonable force is used.
I of course have no idea what the law would be in the US but would imagine it would be similar.
