It's great that we have these laws and the U.S Marshalls to enforce them since a lot of jerks wind up in civil litigation because civil litigation is how one can deal non-violently with jerks who try and screw with people's businesses, and cause damage and harm. These jerks are used to getting what they want through intimidation and well... being jerks. Without this kind of protection, there'd be nothing to stop these jerks from getting their way through continuing their pattern of intimidation.
