mystikmind2000: I disagree, on the one hand you roll the dice on resolving the situation immediately or total failure and no backup. On the other hand, you guarantee that the police will be informed at the earliest possible point.
Also not only do you not know what the bad guy is capable of, you also cannot know what assets the police may have in the area.
Calling the police is a guarantee of at least some kind of assistance over a risk of total failure. The best choice is clear.
Edit: Also while calling the police, if possible, i would follow them from a distance and take down the number plate of any vehicle they boarded.
I was a cop for a time, and I agree from that perspective.
I was a dad longer, and a man longer than that.
The abilities of one human, over another, is not that great that I would risk the life of a child to the abilities of the police to find them later, and in time, to prevent the harm that could come to the child.
I have never been in the kidnapping of a child situation, but I have been in the situation where adults were held captive by nuts, in a sense; both times I intervened non-violently and with success.
One time I was waiting for coffee at a drive through, and I noticed a guy following a few women out of the door. I thought nothing of it, until I noticed that the women were hurriedly trying to get to a bus stop. They were on their way to work, I guess, and the guy was all animated and to the point that I could hear him in the car railing about some capitalist crap. The women were looking like they needed to get away, so I figured I'd do something to "pick him off;" get his attention on me, instead of them.
I got out of the car, approached, and said "I agree bud." He immediately started to rail his non-sensical rants toward me, and I engaged him for the few minutes it took for their bus to arrive. The funny part is that, at the end, he paused, took a look at me finally, and said "you look like management to me." I knew what that meant, but I still had to smile, reassuring him that I wasn't. :-)
Another time, I saw a man and woman huddling on a park bench. I was taking my kids to a baseball game, these people were new to the area and attempting to do the same thing, but a street nut converged upon them and threatened for a handout. I noticed, told my kids to stay back, and "picked him off" too. The couple sure as hell lost no time getting out of there either.
I could go on with stories and details, but what is important is that you can't be afraid to act when you need to. In each of these instances I might have had problems, but I was certainly in a better position to deal with those problems than the others that faced it.
In the end, it is up to you whether you get involved or not. You may not get thanks, you may even get hurt, but in the end it is worth it if you feel you have done the right thing.
