Not sure I follow this. Are you talking about the shoite fans being bashed? If so, then you've picked the right Liverpool club.
If you're worried about violence at games well, there's violence at almost every sport every time there's a game. Happens all over the World. Unfortunately, we share the planet with lots of nutters & it's hard to avoid them.
If you're concerned about violence at a game, any game, don't go. Watch it at home. If you do go, be aware of your surroundings, be mindful of the people you're near, and don't make yourself a target. Simple really.
