Oh, please-it is very upsetting, but "so rampant through our male population"?
There are not ten thousand of these freaks. It is our unfortunate propensity to recycle them that accounts for these crimes.
They are instantly recognizable once they encounter the system, and they are so horrifying to be near that they get moved along quickly to their next stop on the railroad. If jailed, they hone their brutal skills and, in many cases, bask for the first time in their lives in the admiration of their peers, while they together prey on and violate the weak among prison inmates.
The solution is that they should be killed as soon as they come to attention for the first time.
Failing that, they should be permanently isolated in a location without intercourse with the normal world, so they and their fellow sociopaths can live in the type of hell they would inevitably create.
What we're doing now does not work, and we should change.
Unfortunately, through evolution, we've lost out instincts for recognizing predators.
