Why?

Im sure I have complained many times about this and every time it happens, my frustration seems never ending. Vandalism, really, I mean come on the general public. Stuff is put out there for all to enjoy, not just for the select few to destroy. We've had quite a bit of damage over the festive/New Year season. In the lead up to Carols By Candle light, one of the spring based seesaws was snapped off in the middle of the spring. How does one just snap a 1 inch thick spring?!? Yet snapped it was and now the children dont have a seesaw til further notice. There have been countless broken bottles and trashed plants. The damage in the photo really gets me though. The rainbow pillars you see in the shot were installed around Remembrance Day in November last year. They are made of glass and contain information on various wars. They were put in the park, near the War Memorial, as a tribute to the fallen men and women of various conflicts, and to be quite honest, with the the vandalism the way it is at present, Im surprised they lasted this long. The pillar on the end has been damaged and has had to be pulled down so it can be repaired (hence the danger tape surrounding it). People have looked at these pillars and instead of admiring them, decided that they present a challenge of 'How high can I climb?'. So of a night time the drunkards and the mischievous climb the pillars and jump down again. This results in the bolts loosening at the base and the glass panels slipping out of their slots. Dangerous for all involved if they fell, so they had to be pulled down and the bases repaired and goodness knows how long that will take. It can make your job very disheartening sometimes.
