Am I weird for wanting to volunteer for this just out of curiosity?
OK, in that case, the instructor needs to be fired and have all of whatever credentials they have stripped from them, at a bare minimum, possibly criminal charges. Tasers are seriously dangerous, and can kill. There’s no way that using them on innocent people just to let them know what it feels like can possibly be justifiable, even with consent.
Are you just talking about kids or everyone? Many (all?) police officers are required to be tased before carrying a taser and sprayed with pepper spray before being able to carry it.
When choke holds were legal and used regularly, it’s my understanding that all the officers as part of their training were choked out as they practiced on each other.
Skydiving, bungee jumping, & numerous other adventure activities can also be seriously dangerous & can kill; should we ban those activities also? What about obstacle races like the Tough Mudder which has (had?) people crawl thru a mud/water pit with live wires dangling over them?
Presumably the students in this class are interested in a law enforcement/security career. Why not let them experience what they’ll potentially be using in a future work environment? It might give them more empathy to talk down a suspect rather than use something like this on one in the future.
