I am hoping that someone can help me with a title to this movie.

This is a true story and the setting was in the 50's or early 60's.

There was an older man who these punk kids wanted to harass.
There was a group of about 5 kids all between the ages of 18 and 23.
When they approached the house, only two stayed and the rest left.
The two guys went to the roof top where there was a large glass sky
light. By this time, the police had been called and caught one of the
guys in the stair well. The other guy on the roof top had a revoler
with him. His friend who was caught tried to get him to surrender.
When one of the police officers came out of the stairwell and tried
to get the guy with the gun to surrender, he was shot in the forehead.

Both of guys were arrested and went to court. The person who shot the
police officer went to jail and the other person who was caught in
the stair well was sentenced to hang and was hung shortly after the
trial.

The shooter was eventually released from prision and now has a family.

This movie really teaches a very good lesson and I want to teach this
to my kids. I just don't know the name of the movie.

If anyone knows the name of the movie and even some of the actors,
please let me know .

Cheers !

Joe
