The suspects were released?
There were like, what, 9 eye-witnesses plus video evidence? How much more do they freaking need?!
Anyway, props to the guy for fighting back.
Like most things in the legal system, it's a matter of precedent.
Nobody is guilty untill they are found guilty in court (and even then there are appeals). If they aren't (yet) guilty, they can't be detained. If one was detained before trial and then found innocent, imagine the outrage against police for detaining an innocent person.
