This doesn't make sense. If someone is following you in a car, people especially women call 911 because it is creepy and potentially dangerous. If someone is following you in a mall or out walking and you KNOW they are following you there is a problem. Kids are taught from an early age to be aware of someone following them. Trying to make it out like this is normal is silly. It is not normal behavior. It's sick and scary and unnerving behavior. Stranger danger.
I think the reason for being followed is important. For example, is it creepy/stalkerish/etc if my brother follows me from my house to a nearby restaurant? I'd think not. Is it creepy/stalkerish for a soldier to follow someone they think is suspicious? I don't think so. Is it creepy/stalkerish for a concerned citizen to do the same as the the soldier? No, not while reporting every move to a 911 dispatcher.
