Replying to B.A.S.E jump idea

hey guys.
i have completed 11 sucessful jumps and ready to take it to the next stage.
im flying into the us in october for 3 jumps one of grand canyon one of the 3 rivers geourge and a city building in LA.
now my question is two fold. how bad would the cops fuck me over for doing it. and how far is 3 rivers geourge from the nearest cop shop as i am doing a pendulum jump (were you rig a reverse high tension bungee cord shot up higher then the bridge then pull cord.) which will take the best part of 3 hours to set. thanks guys.
