My study is over many years of dealing with redneck scum throwing their hooks of death at any place they feel like. Even if there are swimmers, kids, kooks, and us surfers around. I have asked these self absorbed people over 50 different times to be cautious of swimmers only to be meet with arrogant its all about me responses. My conclusion is that 90% of these people are as stupid as they look. Fight back in a subtle manner remember they usually have knifes in their quiver. Unite surf world.
