It's just how media works and our media is the loudest.

an unusual, infrequent event (such as a man biting a dog) is more likely to be reported as news than an ordinary, everyday occurrence with similar consequences, such as a dog biting a man.

The only perspective people from outside the US have is that from the media. So when they see the man bites dog stories they assume that to be usual and frequent.

I assume the media there does the same thing the media does here. If it bleeds, it leads. Violent news gets top billing, while news of plummeting crime rates isn't advertised.
