Oh no, not common sense and reason? You're no fun at all - LOL!Personally, I think you give the average thug criminal FAR FAR to much credit for thinking about what they are doing and the environment around them. Most thugs likely have an IQ of 75, if that, not that of a sophisticated operator or SEAL, which is what you are assuming IMO. With a simple thug mentality, I think most of them know the sound of a racking gun and 99% will run not looking specifically for a gunfight or to be killed. Personally, I'd rather have them run from the simple sound of a gun than engage in a firefight.
We can all talk a big game here, but I'll wager nearly 100% of us would never want to engage in a fire exchange, particularly inside our homes. Being all sneaky and quiet almost ensures that guns will be fired in order to scare away or terminate the threat, and honestly that's the last thing any of us want.
