Attacking Landon is a pretty pants-on-head-retarded move... He might not be a super-badass... he's a pretty inexperienced vampire... though the US government conveniently has pamphlets for everything.
...But he's got army training and happens to be six feet tall in addition to being a vampire, so he's at least above average in ass-kicking aptitude.
Landon thinks himself a Friendly Neighborhood Vampire.
And he isn't very fond of people who adamantly think he's evil, though he never really angsts about it beyond momentary grumbling. Landon isn't the sort of guy who gets upset for a long time.
Killing vampires is on shaky legal ground in Landon's universe, but the fact that dead vampires decompose easily makes stopping people kind of hard for lack of evidence of the crime.
...I'm not sure if vampires show up on camera or not. I think I'll say yes and blame a technology-geek of a porn director inventing one because he wanted to fap to vampires having sex very badly.
Never under estimate human ingenuity when it comes to sex and violence. :<
Stakes (metal or wooden) are the traditional vampire-slaying method, but guns work fine assuming you add enough gun. And if that doesn't work, ADD MORE GUN.
