Uhhh, we do not know this is what happened as only what the officer said as he tried to spin his failure to be professional. 

Fact is the rookie did not know what to do, panicked, lost it all. Firing 7 shots. Really? 

If you have ever watched Alaska State Troopers they deal with guns in cars every day. Know just about everyone is packing. Do not panic and over react like this rookie did.
