keyed

Some ******* (Edited by Acura4Life) just keyed my MDX in the parking deck where I work. Three big, deep scratches along the driver and rear driverside doors. Down to the primer. Both doors have to be painted.
Why do people do that? What possible benefit did this ******* (Edited by Acura4Life) hope to gain?
In this time of national crisis and unity don't people have more important things to worry about?
