but we still have the right to a jury
The LAST thing you want to depend on in this political environment is a jury. Zimmerman was lucky. The DOJ sent down agitators to create "protest" marches, etc., and then forced the State to go against Florida's "stand your ground" law and prosecute Zimmerman. Add to that the tremendous amount of biased coverage (showing almost baby pictures of Martin while showing the meanest looking ones of Zimmerman they could find, having "experts" convict him in the media, etc...) But, the evidence didn't back up the claims of the State. Recently, one juror, who wasn't able to make a case in the jury room is out in the media saying that "Zimmerman got away with murder". Now, that is being used by the Anti-Constitution crowd to say "we told you so", as if it were some kind of irrefutable proof of misdeed.
The odds are that if you don't pursue the perp will attack someone else, but you are not responsible for that.
