While I don't want either pointed at me, pepper spray and tasers don't quite demand the same respect that a gun does. I've watched every episode of the show Cops and every Police Academy movie, so I'm pretty much an expert in law enforcement (give or take a few minor details). Pepper spray and tasers don't always work, so when you're in the midst of a life threatening event like of a stabbing, a gun is the tool you need to take down the perp (that's police lingo, google it if you don't already know).
