Execution ideas?

First of all, a big TW for possible descriptions of death. Please add a spoiler to any graphic descriptions if you can. (To hide text within a spoiler, wrap it in the tags. Text in a spoiler needs to be on a new line.)

Anyways, I'm planning a fantasy story where there are people that have magic, like telekenisis, telepathy, and other things like that. What would be a good creative execution method?

Yeah, like government sanctioned kill people type execution lol. Like if normal people tried to execute someone that had like magical powers and stuff, how would they do it?
