Public or Private Land
I am a professional photographer. The key to this whole thing depends if the games are on public or private land. If it is public land, then you may be in for a fight. At the same time, many sports parks are owned by a private company whom rent out the fields to organizations. The photographers then could be charged with trespass.
Also, nothing in any law says that a person can’t stand in front of a photographer. You are given the same rights as they are in a public place. You just can’t touch them in any way, same goes with them. They can’t touch you. If this is done, assault charges can be filed.
Finally, If the photos are used in any way as commercials to promote the company, then yes you can sue them for not having a model release.
It sounds to me as this person doesn’t have a lick of sence.
