We have seen it before, criminals have thrown rocks, the weight of their own bodies and other objects at windows or glass doors to get in to a business illegally, only to find out the glass is too thick or strong.
The following is another one of those situations:
In Prince George, MD a criminal was caught on surveillance trying to break into a business with a brick. Not only did he try to break the bullet proof glass 3 times, his 3rd attempt was the best. The brick ricocheted back at him and hit him in his face.
