In the state of Pennsylvania, is it legal to videotape someone
speaking at a public event if they have full knowledge that the event
is being filmed, but say they do not consent to be videotaped? The
event is held indoors on private college property, but is open
invitation to the community. The camera is set up before the event
occurs. At issue is whether one is legally obligated to stop filming
at someone's objection, once they are already speaking in front of the
camera. Citations appreciated.
