A public execution and glass camel

I was in a sports arena with a collapsable high-tech weapon in my backpack. I assembled it - it had two modes, an energy beam mode and some sort of pellet mode that fired a stream of tiny bullets by magnetism. I aimed it at someone across the arena and it indicated it locked on by making a computer graphics style outline appear around the target's body. I realized it was a really powerful weapon.

There was to be a public execution and I was the executioner. The execution wasn't the main event, but entertainment during half time. This all seemed very normal to me.

I took my place at the top of a basketball free-throw line with the condemned man at the other end. The man said the evidence against him was wrong. A key piece if evidence was that the killer had a friend with the flu. The man showed me an old newspaper article about a friend of his while he was a child having the flu. As that was years ago, he couldn't have been the killer as the murder was recent, he explained. He then said he wasn't afraid to die.

His explanation of innocence made sense to me and it seemed normal and regular that I could decide to cancel the execution. A statue of a camel made of milky glass approached the condemned man. An oversized dental drill coming out of the camel's mouth moved towards the man - I assumed it was going to torture him. I shot off the head of the torture device with the energy beam.
