A tip for you all when you need to damage small objects without getting caught:

Make the best slingshot you can, train your aim and shooting strength, wait for a heavy rain day and shoot ice cubes at it. The rain will impair visibility and muffle the impact sounds, making it much harder to spot you, and there will be no evidence of what hit the object. Also, there’s nothing illegal about having a slingshot with you. The rain can make it harder to hit the object, but a few attempts will allow to learn compensate for it
