A recent example is the domestic abuse victim in my complex who has setup private surveillance cameras in the indoor common areas that are heavily trafficked by other neighbors, none of whom have given their consent. She does not consider warrantless surveillance of others (or calling the police on those of us who do not wish to be surveilled in a secure area of the building by her personal cloud camera) to be a violent act, nor does she consider threats of calling the police on those who shield themselves from her camera’s view to be an act of violence.
Violence is not limited to physical actions that induce physical harm, it is any action intentionally designed to reduce the safety or security of others - physical, mental, fiscal, political, etc.
