I agree with the point she was trying to make. As a member of the public she should not have been arrested for being verbally abusive. But I'm OK with her being removed for subjecting the people who work there to that abuse. If she had made the same points with something approaching civility I'd be in her corner, as I still am with respect to surveillance.
If she were a coworker directing that to me, one of us would be a former employee by the end of the day.
