Javelnia are not that aggressive, but they are not afraid of people or culture and can integrate readily into neighborhoods where there is sufficient habitat, just like many other animals often do. However, they are wild animals. Keep in mind that those purdy non-aggressive deer injure a bunch of people each year and even kill a few in "deer attacks" (never mind the vehicle-deer collisions). http://usatoday30.usatoday.com/news/nation/2005-12-01-deer-attacks_x.htm
As noted, this is a numbers game and there are a lot of human deer encounters and a certain percentage go bad. As a result, you are more likely to be injured or killed by a deer than by a wolf. If you do a little digging with Goggle, you will find that more people are "attacked" every year by deer than by mountain lions and bears, combined.
Javelina attacks are very rare, but as with so many of these animal attack stories, it is likely that the animals were not so much attacking as they were defending themselves from a threat, the woman and her dogs. More than likely, the problem was the dogs that the javelina were defending themselves against, but she went down in the process and sense she was with the dogs (holding them on leash?), she got bitten in the process. She likely was not the focus of the "attack."
With that said, the dogs were just doing what dogs do, more than likely, and barking at the javelina they saw.
In fact, she was walking them on a leash and the javelina went after the dogs. Also turns out that a neighbor had been illegally feeding the javelina.http://www.azcentral.com/story/news/loca...ttack/84060746/
