I watched a problem a few months ago about this problem. Of course they probably exaggerated a bit, but the boar population is increasing dramatically, and yes, they are VERY hard to thin out, they breed like crazy, can eat just about anything, and are potentially very dangerous to humans and animals.
Where I live, I have seen wild boars, know people who hunt them, and the stories are impressive. Single wild boar taking out a couple of trained pit bulls. Taking several shots before finally going down. It really is becoming a problem nation wide.
Some hunters in TX use Great Danes. I have a 5.5 mo. old Dane puppy who's nothing but a love muffin who lies to sleeep with me (I know, the Dog Whisperer and the Dog Lady would both say I've allowed him to develop a terrible habit). He probably wouldn't qualify.
No it is not a nation problem, it is national hype. Most of the so called wild pigs are wild pot bellies, where idiots were buying them for pets a few years back, they got tired of them and turned them loose.
here in Michigan they are spreading throughout the state. I recently read an article in the local paper about a resident here in S.E. Michigan (New Baltimore) seeing one in his back yard.
I guess the hunting laws say you can shoot them on sight, any time of the year, but you have to have a hunting license..........
It doesn't address the issue of local ordinances which ban the firing of weapons within their city limits..........
