in spite of this slight increase, it's hardly a pattern. Seriously people, stop blowing this kind of news out of proportion and get a hobby.
there is no increase, it simply is only now being reported to the public for their safety thanks to thousands of citizens out there posting it on forums and youtube, which did not exist in previous decades.
the violent sh__ has been going on for many decades, I personally have suffered of it since the mid 1970's and I'm certain it wasn't a new thing then.
the media simply REFUSED to print it because they wanted to act like families and law-abiding peaceful people were safe.
you sound like a wimp apologist, I hope this kind of suffering is inflicted on you many times, you have earned it and deserve it.
eventually the law-abiding with balls and who speak the truth will leave you apologists behind in the dust to suffer from the violent pieces of sh__ you are apologizing for. they will kill off their host (you) and then they'll starve to death.
