That Kemal, is a paradox.

This is all just a rambling of a Poli Sci major, mind you.
Entirely IMpossible regardless of SLoT or DLoT, since in order to have travelled back in time holding a loaded gun, he must have created a wormhole, loaded a gun, and then stepped into said wormhole.... thus the unsolvable paradox

Both Static and Dynamic Lines of Time would require the actions leading up to the event to occur, in order to create the situation causing the paradox.

For a colloquial example, refer the movie "The Time Machine" starring Guy Pearce. Inventor creates a time machine in order to go back in time to save his fiance. However, since the death of his fiance was the reason he thought of, and thus created, the time machine, it becomes an unchangeable event. If he saves his fiance, he wouldn't have the idea to create the time machine he is using in order to change the past.

Alternatively, there's Ben Elton's theory that it doesn't matter if you become your grandfather anyway, since the universe will sort it all out later.
