There is something weird about the story of the alleged assault of Sen. Rand Paul (R-Ky.) by his neighbor. We know this: Paul was attacked so violently that it broke six of his ribs and dislocated some others. According to Paul’s own accounts, his dislocated ribs have caused the very serious side effect of swelling and fluid around his lungs. But what we don’t know, several days later, is why the attack happened.

Initial reports suggested the alleged assault could have been the result of a long simmering dispute with the neighbor over landscaping issues. The lawyer for the neighbor who allegedly attacked Paul said the matter in dispute is “trivial.” I guess that’s possible; feuds with neighbors can be trivial, but bitter. Yet one would think, in gated communities such as Paul’s, they usually turn into legal battles not physical ones. And to break someone’s ribs is not a trivial attack. And to make matters more confusing, those accounts of the reasons for the assault were thrown into doubt by Paul himself who coyly tweeted news accounts questioning the explanation of the disagreement being about plants and shrubs. More dark speculation about motive has centered on the attacker’s supposed opposition to Paul’s political views.

Again, what is going on here? Where is the Capitol Police in this story? Aren’t they interested in knowing why a member of the U.S. Senate was beaten so severely? And most of all, why doesn’t Paul tell us what he knows instead of just sending tweets that reinforce the severity of his injuries, cast doubt on the reasons for them and serve to do nothing but deepen the mystery?
