In need of a legal lesson apparently
"after he shoved me in the chest"
That right there is simple battery my friend and Odor would be justified in escalating the confrontation to a level sufficient to end the assault.  It happened in his place of work and he has no reasonable expectation of retreat.  
I suppose you think hockey players that drop the gloves and go at it should also be arrested?  Or what it a boxer throws a deliberate low blow, should that be cause for arrest?  Go watch cricket man, or badminton, or curling.  You would have put Nolan Ryan in jail to I guess?
