A broken nose is not an uncommon injury if you get into a fight. What is the relevance of a broken nose to our knowledge that ZImmerman followed Martin, and then shot Martin.
In case you don’t know this, following someone is not a crime and certainly does not justify the person being followed launching a physical atatck.
And you want to know what a broken nose has to do with a person’s claim they were attacked? Because a broken nose is a “common injury”?
Ive watched many a prize fight in which no one’s nose is broken, and I’ve been in fights without breaking or getting one broken.
I’d say a broken nose in a fight is not common.
