DO WE NEED A GUARD ON THE FLOWERS WE PUT ON GRAVES IN THE CEMETERY?

EVERY YEAR WE HEAR FROM LISTENERS WHO HAVE PUT FLOWERS OF THE GRAVES OF LOVED ONES, ONLY TO HAVE THEM STOLEN.  I FIND IT HARD TO IMAGINE THE KIND OF LOW LIFE INDIVIDUAL THAT WOULD DO THIS, BUT IT IS VERY DISTURBING TO THE PEOPLE WHO HAVE TAKE TIME AND MADE THE EFFORT TO PAY HOMAGE TO SPOUSES, CHILDREN, PARENTS OR GRANDPARENTS EVERY MEMORIAL DAY.  IT IS NOT ONLY IN HOLLAND, BUT IT HAPPENS IN OTHER LOCATIONS AS WELL.  

PERHAPS WE ARE NOT INSTILLING IN OUR CHILDREN, THE SPECIAL MEANING A CEMETERY HAS IN THE LIVES OF MANY OF US.  

ANY IDEAS ON HOW WE CAN STOP THIS VANDALISM?
