A police boat crashed into two other boats that were docked on the Potomac River in D.C. on Saturday.  According to a police spokesman, the cop driving the boat just misjudged how close the other two boats were.

 

 

There's video where you can see him making a quick U-turn, then he GUNS IT and sideswipes both of them.  And one of the boats was damaged enough that it started sinking.  (Search for "5-0 Going Woozy!")
