Rabbi Bassous devoted his speech this past Shabbat to learning from the cemetery vandalism in New Brunswick. I missed the speech (my daughter had other plans for me), so I apologize in advance to Rabbi Bassous if I botch my summary of what he said. My husband related to me that he spoke about two topics:
1) Even when you are dead, you may still not be at rest. Vandals can still attack your grave.
2) It is important to raise children from an early age to respect property. This can start with teaching children to pick up a candy wrapper from the floor. Unfortunately, the teens involved in this incident were not raised to respect property.
My husband pointed out that if the teens were tried in a Jewish Halachic court, they would be considered adults. In the American judicial system, they are considered juveniles.
In my searches on the web, I discovered that cemetery desecration is all too common a pastime for some teens. Clearly, there are a lot of parents out there NOT teaching their children to respect property, especially buried dead people. On one forum, I found young men bragging about their exploits, and saying the only reason why this is getting such publicity is because it is a Jewish cemetery. Sad. And scary.
