“In many of the cases, it's a crime of opportunity. A group of teenagers is roaming the street on a hot summer night and they come across a homeless person who might be mentally ill or alcoholic. When they hurt a homeless person, they think they can get away with it -- and they think they won't be hurt in return.”
“They do this because they think they can, that they can get away with beating a homeless person and nobody will care, and the homeless won't be able to fight back.”
