Why do people destroy potentially functional discards?

There's a big-screen TV on the sidewalk on Delta, near the Wal Mart, and it's been there for a couple weeks. It was being dumped, obviously. After a few days, someone punched or kicked the screen in, basically destroying it. Why did they do this?

Creating this big TV took a lot of fuel, and it contains parts that could be used by someone interested in making a projection TV or using the lenses for something else. Now, it's trashed. It will have to be dismantled as e-waste, and dumped, with the toxics going to appropriate places.

We're just an affluent, wasteful community.
